elodea photosynthesis graph

Abstract This study was undertaken to determine the relationship of different wavelengths of light and the rate of photosynthesis in spinach leafs. Like the Cathedral tunes, the light reminds her of desolation. From which kingdom is this organism? Compare the action spectrum to Elodea's absorption spectrum, ... More complex spectrophotometers can also produce a graph of measurements over time. ... are absorbed by the photosynthetic pigments in plants. // Provide alternate content for browsers that do not support scripting // or for those that have scripting disabled. Elodea plants are native to the New World, though a number of species have established themselves as invasive ): To correct for this representation of the data and present a graph that shows increasing rates of photosynthesis with a positive slope the ET50 term can be It is extremely important to know the meaning and process of photosynthesis, irrespective of the fact that whether it the part of one's curriculum or not. Thus, these short wavelengths have more energy and thus are optimal for photosynthetic activity. In this experiment I wanted to find out in what condition the elodea plant can grow and photosynthesis the best. The rate of photosynthesis varies greatly with changes in wavelengths of light. The rate of photosynthesis is often measured at different wavelengths of light, using the same sample of plant pigments. D. Wavelength and Photosynthetic Rate. It can be seen from this table that the blue colour group had the most average bubbles per day. (series). 022; Ishanka Hemachandra; February 16th, 2017 Elodea canadensis, within six species of aquatic plants was derived from North and South America. Green light has a shorter wavelength than the red light but it had a lower rate because chlorophyll, the photosynthetic site, reflects the green colour and absorbs all others. This explains why the Elodea plants are green. Plants have four types of pigments, namely chlorophyll, carotenoids, anthocyanins, and xanthophylls. Waterfowl, especially ducks, as well as beaver and muskrat eat this plant. 2) Crush the end of the stem at the site of incision gently. (2) Pour equal amounts of bromothymol blue into the test tubes or glasses (about 2/3 of the test tube or ½ cup in a small glass). The diagram given in this BiologyWise article is a small pictorial elaboration of the process of photosynthesis that will prove helpful for kids and teenagers to understand this vital process of the plant kingdom. The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source, the lower the light intensity and so less photosynthesis would take ... Another error that was in my experiment was the fact that the elodea plants were bought from two different stores. 8. Plug the 100 watt light bulb into the socket and switch it on. Plants have shown to produce more bubbles when, placed closer to a light source than further away. I then filled each ice cream container with 500 ml of water and put above each container a 100 watt lamp attached to a stand distanced 20 cm from the container. Table 2: Light colour and the average length grown (cm) in five days. Table 1: Light colour and the average number of bubbles per day. At low temperature, the enzyme does not have enough energy to meet many substrate molecules, so the reaction is slowed. 6. Because of this for my repeat I had to make some major changes, I removed the lamp and decided to measure the length grown in each segment of elodea after 5 days. In order to test the light colour effect on the photosynthetic rate of the plant I decided to cover the ice cream container with coloured cellophane, I chose four colours Green, Red, Blue and purple. This is because these colours contain more energy, for according to the colour spectrum, they are of shorter wavelengths, and the shorter the wavelength, the more energy is present. Cover each ice cream container with a cellophane plastic (purple, blue, green and red). Graph the … A photon ... As shown by this experiment, photosynthetic rate varies greatly depending on the different colours of light used. Observe the plant without the use of the light source. With the temperature rising to 35 degrees to 40 degrees, the photosynthesis rate also increases, but the rate dips beyond 40 degrees. So I predicted that the plants under blue and purple colour cellophanes will have a higher photosynthetic rate. Materials Needed: (For each group of four students) elodea (water plant) lamp (40 watt) 3) Submerge the plant into a test tube filled with 40mL room temperature water and 1g baking soda. Slice off a portion of the stem at an angle and lightly crush the cut end of the stem. The efficiency of photosynthesis can be measured, by the amount of oxygen bubbles formed during a given amount of time. only the ones that floated to the top of the test tube. It can even continue to grow unrooted, as floating fragments. The results from my very first experiment were unsuccessful. The mixtures of DCPIP with water, PO4 buffer, and chloroplast will be prepared in a number of cuvettes. This explains why the Elodea plants are green. Elodea is a fast growing aquatic plant, it has a high photosynthetic rate and it leaves entirely under water but it can even continue to grow unrooted, as floating fragments. 4. Learn vocabulary, terms, and more with flashcards, games, and other study tools. This data might only be valid on aquatic plants, so for the next experiment, the same tests can be applied to land plants that require soil. Graph). (My second method was successful). 4 cellophane plastics (red, blue, purple and green). Keep the ice cream containers (filled with water) away from the socket. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. The above is the method I used for my first set of experiment. The elodea was attached to a scale and syringe that was used to pull through oxygen bubbles so we could measure the rate of oxygen released and relate this to the rate of photosynthesis. The purpose of this experiment is to find out under what wavelength (different colour of light) the elodea plants are able to grow and photosynthesise the best. In paper chromatography, the pigments will separate based on their ... Elodea often overwinters as an evergreen plant in mild climates (like New Zealand). Elodea, genus of five or six species of submerged aquatic plants in the frog’s-bit family (Hydrocharitaceae), useful in aquariums and in laboratory demonstrations of cellular activities. They were all like vines ... in plants subjected to green light verses plant growth in plants subjected to red light. The elodea was placed in these temperatures and a light shone on them for 5 minutes. The problem with ET50 is that it goes down as the rate of photosynthesis goes up--it is an inverse relationship and creates the following type of graph (data from Steucek, et al. This test will allow us to see which wavelength (colour) will allow the most light the elodea plant needs to flourish. ... not fall over. 1985. Table 3. 11. Elodea, an aquatic plant available at many pet or gardening stores Bromothymol blue solution (acid-base indicator available for purchase online) 0.04% (Aqueous), 1 L Bottle (1-2 bottles) Transparent plastic films of different colors (heat resistant) 1. Count the bubbles to measure the rate of photosynthesis. Too much light may cause plants to "burn out" while too little light will not provide enough light for optimal photosynthesis activity. Change the conditions of photosynthesis by altering light intensity and carbon dioxide amount, and determine the effects on the photosynthesis rate. Hypothesis: Yes, light intensity does affect the rate of photosynthesis. This will be measured by counting, Amount of baking soda in each test tube-1g. Light’s colour is determined by its wavelength of light, and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. 1) Cut a segment of the Elodea plant approximately 8cm with scissors. 6) Turn on the light source and begin taking observations. Graph 2: Light colour vs length grown (cm), (Table 2. This is the rate of photosynthesis at that particular concentration of CO2. adequate amounts of carbon dioxide for photosynthesis to occur. OXYGEN EVOLVED. Here you can order a professional work. It should be noted that I used a very dark blue cellophane colour; my purple cellophane colour was light so it is possible that if I used darker purple colour cellophane it might have produced a different results. Obtain 3 pieces of Elodea about 6 cm in length and 2 pieces of aluminum foil. RESULTS: Create 2 separate bar graphs comparing the average plant growth and color of light. 1. I repeated the experiment, but this time I decided to remove the 100 watt lamp and instead of measuring the ph of water measure the number of bubbles on each plant everyday and on the fifth day the elodea segments were removed from the container, measured and recorded again to see the amount grown (in length) during the five-day period. Silty sediments and water rich in nutrients favour the growth of American waterweed in nutrient-rich lakes. Therefore varying wavelengths of light have drastic affects on the rate of photosynthesis. Label 4 screw cap tubes 1, 2, 3 and 4 with a marker and line them up in order in a test tube rack. Because of this, the plants from one store can be of a completely different species than the plant of the other store. Lab room light will be used for the control light. These graphs have been plotted with rate of photosynthesis against the factor under investigation. 7. This is not an example of the work written by professional academic writers. Elodea. 2. Dickinson ... All Papers Are For Research And Reference Purposes Only. Free Samples and Examples of Essays, Homeworks and any Papers, Filed Under: Term Papers Tagged With: light. To eliminate this built in error, what can be done is to order the plants ahead of time so that one store does not run out of the materials and so there will not be a need to go to another store. Graph 2: Light colour vs length grown (cm), (Table 2. Then a comparison can be made between the similarities of aquatic photosynthesis and growth to that of terrestrial plants. The red light and green light will have lower photosynthetic rate because red light has a shorter wavelength (lower energy) and the green light is absorbed by the plants chlorophyll pigment. I use this plant because it will grow in a wide range of conditions, from very shallow to deep water, and in many sediment types. Fill each ice cream container with 500 ml of water. Bromthymol blue is used as an indicator for the presence of CO2 in solution. Besides the light factor I also decided to put a 100 watt lamp above each plant so I get a high light intensity to speed up the rate of photosynthesis. In this experiment, the light intensity is changed by changing the distance of the source of light closer or further away from the elodea, so theoretically, when the intensity becomes stronger due to the light source being closer to the Elodea, the rate of photosynthesis should increase and therefore the number of oxygen bubbles will increase too. I thought that the water in the container that had plant with the highest photosynthetic rate would become acidic because more carbon dioxide is produced by the plant in respiration. These graphs have been plotted with rate of photosynthesis against the factor under investigation. Time is the independent variable and will be measured with a stop watch. Answer question 4 by making a Line Graph of the data in Table 3. In this experiment the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of Elodea or Cabomba. In each experiment that I did 4 segments of elodea where used each segment was cut to exactly 10 cm long and each elodea segment was placed in an ice cream container covered with a different coloured plastic cellophane for the next 5 days. 4. Specifically, identify the pigments on each strip and compare their positions to one another. This activity will allow students to measure the rate at which the photosynthesis process occurs. Elodea High School Inquiry/Scientific Method Plants. 9. The rate of photosynthesis is measured by one of the following methods: By measuring (I) the volume of CO, consumed (2) volume of oxygen liberated (3) amount of carbohydrate accumulated. So for my next set of experiment I decided to remove the lamp and instead of measuring the ph of water measure the length grown after 5 days and also the number of bubbles present on the plant everyday. Place the 10 cm segment of elodea plant in each container. Introduction. Recently there are ... light Waterproof caulking Methodology Preparation of the Nutrient Solution The nutrient solution will be stored in an appropriate container; ... every other day while the plants are still ... ... the exit of winter light at the end of the day in the same distant ... and joy. Measure the ph of water using the ph meter. This is probably caused by the lack of oxygen and carbon dioxide circulation inside the ice cream containers. 4) Set the test tube on the test tube rack. Does light intensity affect the rate of photosynthesis in Elodea plants? Before they begin the experiment, however, students must come up with a well-worded hypothesis to be … Disclaimer: This work has been submitted by a student. An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. Photosynthesis is one of the most remarkable biochemical processes found on Earth and allows plants to use sunlight to make food from water and carbon dioxide. BIO 101 Lab 08: Photosynthesis 6 I averaged the number of bubbles altogether eg I had 3 recordings for every colour per each set of experiments. The aim of this experiment is to use two kind of spectrometer to identify the atomic spectra of different atoms. Biology 4A Photosynthesis Laboratory (03/2020) Page 3 of 3 . Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, pH and intensity of light. This is because different colours are determined by different wavelengths, and some wavelengths are shorter than others. And the number of bubbles on the elodea segment everyday. 8) Repeat steps one through seven for the following light distances: 9) Lastly, lab room conditions will be used as the control group. The photosynthesis process rate varies from different wavelengths and intensities of light. 7) Count the number of bubbles generated the following intervals:10 second, 30 second, and 60 seconds for each trial. I decided to measure the ph of water after 5 days to see if there are any changes in ph. I predict that the plant under blue and purple light will have a higher photosynthetic rate because according to the colour spectrum, they are of shorter wavelength thus they have a higher energy. Question 24 . 91 Exercise 1 – Observing Photosynthesis via CO 2 Consumption 1. Explanation. Table 2: Light colour and the average length grown (cm) in five days. I find out that the elodea plant is a genus of aquatic plants. Describe what each of your chromatography strips looked like. There were always light source that will influence our experiment. The ice cream containers were sealed for 5 days so the level of carbon dioxide in the container was probably not enough to sustain photosynthesis and therefore causing the plant to produce fewer bubbles. Measure the ph of water in each container after 5 days. Keeping that in mind I set up an experiment to find out under what light colour (blue, green, purple and red) elodea can photosynthesis the best. I got the same ph 8 for all the containers. It can be seen from this table that the blue colour group had the most average Length grown (cm). This lab involves the qualitative measurement of the changes in carbon dioxide concentration associated with respiration and photosynthesis in the freshwater plant Elodea. Remove several leaves from around the cut end of the stem. Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. Make sure your hands are dry when plugging the lamp. The Hydrogen Spectrum colour| θ2-θ1| (θ2-θ1)/2| λ| accepted| difference| red| 46.483| 23.242| 657| 740| 11.2%| blue| 33.963| ... ... experiment, we will measure the photosynthetic rates of spinach disks under different wavelengths (blue, yellow, green, red and white) of light. The punched out leaf disks will initially sink in a test tube of water but will float as photosynthesis occurs. The purpose of this experiment is to see under what conditions the elodea plants grow and photosynthesize the best. It is the simplest method. Here you can order a professional work. By conducting this experiment, I was expecting to see as I mentioned in my hypothesis a heightened photosynthetic activity using purple and blue light. Silty sediments and water rich in nutrients favour the growth of American waterweed in nutrient-rich lakes. To accomplish this, the plants were subjected t different light colours (Blue, Green, Red and purple). I first did some research on the elodea plants niche. The rate of photosynthesis was measured every five min under light colors of white, green, red, blue and yellow under a light intensity of 2000 lux. It is native to North America and is an important part of lake ecosystems. Study the number of bubbles formed (dependent variable) as a function of time (independent variable) at various light distances from the test tube. The closer (from 50cm to 10cm) the lamp was placed to the test tube, the more bubbles formed over 60 seconds (from 110 to 201 bubbles). The bar graph shows the numbers of some of the organelles in one of the cells from the organism. This experiment was consisted of 4 different colours of light, Blue, Green, Red and Purple. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea? The ice cream containers were sealed for 5 days so the level of carbon dioxide in the container was probably not enough to sustain photosynthesis and therefore causing the plant to produce fewer bubbles. Initially I decided to measure the ph of water after 5 days but the results were not successful as you can see in my results table. Activity Option #3 – Role of Carbon Dioxide and Light (1) Set up the lamps at least several feet apart and away from windows. Answer questions 5 and 6 based on your Line Graph 10.Answer question 7 based on the results of both Experiment 1 and Experiment 2. Students will work in small groups to design an experiment with one independent variable and test this variable on spinach leaf disks. (For my daily results refer to my log book). We learned to use the calibration curve obtained from a known spectrum or measure the angle of diffraction to find out the wavelengths of unknown spectral lines. The data I collected and my graphs show that my hypothesis was right. This is probably caused by the lack of oxygen and carbon dioxide circulation inside the ice cream containers. (Find a price that suits your requirements), The Term Paper on Photosynthesis Lab Report, The Term Paper on Light Quality On The Rate Of Photosynthesis Measure, The Essay on Plant Pigment Chromatography, The Term Paper on Spectrometer Experiment, Light Quality On The Rate Of Photosynthesis Measure, Emily Dickinson’s “A Certain Slant of Light” Analysis Essay. The feeling of ... no definitive answers in regards to the light or the speaker’s internal despair. According to this trend line, the light intensity increases while the rate of photosynthesis increases as well, thus the independent and dependent variables have a positive correlation in this stage of the graph. The Effects of Light Intensity on the Rate of Photosynthesis of Aquatic Plant Elodea Bethany Rollen Morgan Daniels, Victoria Rosario, Natali Mejorado Biology 1441 Sec. As light intensity reduces so bubble count reduces. Does photosynthesis performed by elodea remove CO2 from the water? 5) Place a light source 50cm away facing the test tube. For my repeat experiments I made some changes. I first did some research on the elodea plants niche. From the results that I collected in my log book for my second method it can be seen that the number of bubbles on the leaves of the plants generally decreased each day as the days passed. Photosynthesis defines the process by which plants and some bacte… The last day the green light plants were all over the tray container. It provides good habitat for many aquatic invertebrates and cover for young fish and amphibians. Dissolved Oxygen production of . From this experiment, I can see that there is a significant variation in the effectiveness of different wavelengths of light upon photosynthetic rate. Measure 500 ml of water using a beaker. I also averaged the results for the length grown for each colour by adding all my results together and dividing the outcome by 3. However, this increase is not exponential and it is seen that when the temperature rises to 45 degrees, there is a decline in the rate of photosynthesis. In the results the pattern is that when the light intensity is higher the readings are generally higher. Graph). Elodea is native to North America and it is also widely used as aquarium vegetation. I found that the rate of photosynthesis increased with temperature. ... g Plot data on a line graph. photosynthesis. The basic structure of these plants are whirls of leaves around a stem that form a chain of long segments connected to looks like pipe cleaners with usually a diameter of about half an inch or so, depending on the species of elodea plants. The, oxygen bubbles are a product of photosynthesis. This would then allow white light through but making the holes small and on the side of the container will reduce the amount of light through that is not of the colour group. I did 3 experiments so altogether I collected 9 results for every colour so I added all the 9 results and divided the outcome by 9. 3. Place the sprig in a test tube, cut side up. SURVEY . With With each graph, make sure to include a title, equal intervals, labels for the x and y axes, and a key / legend Photosynthesis increases with the increase in temperature. Tags: SB1.e . I also realised that my plants are dying because of the high temperature produced by the 100 watt lamp. Background Emission Spectrum As we know, every atom has a set of discrete energy levels occupied by its electrons. Since the oxygen bubbles are a product of photosynthesis, one can conclude that the more bubbles formed, the more photosynthesis occurred, thus increasing the rate of photosynthesis. Graph the results placing temperature on the x-axis. Graph 1: Light Colour vs average number of bubbles per day (Table 1. When the temperature rises, the particles in the reaction move quicker and collide more, so the rate of photosynthesis rises also. Graph) Discussion: In this experiment I wanted to find out in what condition the elodea plant can grow and photosynthesis the best. under different wavelengths of light. How ever the green light photosynthetic rate was lower than the red light photosynthetic rate. 1) Cut a segment of the Elodea plant approximately 8cm with scissors. The dependent variable will be the number of bubbles formed and floated to the top of the test tube. The photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. 5. It this case, number of bubbles of oxygen are counted given out in unit time by green aquatic plants like Hydrilla. 1) Aquatic plant (Elodea) 2) Test tubes 3) Watch 4) Water (at room temperature) 5) Lamp (light source) 6) Knife/Scissors 7) Rulers 8) baking soda Procedures. I find out that the elodea plant is a genus of aquatic plants. Add water to test tube and a pinch of baking soda. Photosynthesis is a food making process for algae and plants. 2. Factors Affecting Photosynthesis-Interactive. Start studying Elodea and Photosynthesis Lab. The values for the factor being varied should be on the x-axis, and the mean bubble rate in … Other follow-up experiments that can be done are to test other colours instead of the ones in this experiment like black lights and UV lights and light intensities of a wider range or an experiment to test the effect of temperature variations on the elodea plants. These pigments have different polarities and chemical properties. The gas should be checked to prove that it is indeed oxygen - relights a glowing splint.
