Textbook Reference: 6.4 What Are the Active Processes of Membrane Transport? To Study the “Dark Reaction” of Photosynthesis 4. Cellular Respiration Virtual Lab Carbon Transfer Through Snails and Elodea Background: All organisms are dependent on a healthy carbon dioxide-oxygen balance. All living things use a process called respiration to get energy to stay alive. 1. Cellular respiration in plants is the process used by plants to convert the glucose made during photosynthesis into energy which fuels the plants’ cellular activities. Examining the interactions between Elodea and snails by detecting the presence of CO2. ADVERTISEMENTS: Expt. We did this by using a Gilson Respirometer and samples of Elodea plant placed in H2O and NaHCO 3 solutions—both of which were operated under lighte d and darkened external conditions—to measure the consumption of CO 2 during photosynthesis and the production of CO 2 during respiration. However, the color change in the dark showed appropriate production of CO2, this can be concluded because the presence of CO2 created a green/yellow color from the original color (blue). Animals breathe. For this reason, it is also expected that the color of bromthymol blue will change colors throughout the duration of this experiment due to changes in the CO2 level in a sealed test tube. H Requirements: Few branches of an aquatic plant, i.e., Hydrilia, etc., beaker, glass funnel, test tube, sodium bicarbonate, etc. Experiment – 1: Object: ADVERTISEMENTS: Demonstration of Release of Oxygen during Photosynthesis.

Photosynthesis-Elodea Lab Photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar. Depending on the amount of sunlight, plants can give out or take in oxygen and carbon dioxide as follows​1​. Dim sunlight – Photosynthesis rate equals respiration rate. During daytime, photosynthesis produces oxygen and glucose faster than respiration consumes it. The photosynthesis-cellular respiration experiment that we conducted on elodea can be set up to compare the rates of photosynthesis and cellular respiration in other conditions, like winter and spring. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Teaching Topics. The plant I usually use for this experiment is called elodea, which is available at any local pet store in the fish area. Plants use carbon dioxide and produce oxygen gas during photosynthesis. Copyright © 2020 rookieparenting.com. Photosynthesis and Cellular Respiration Virtual Lab Carbon Transfer through Snails and Elodea Background: All organisms are dependent on a healthy carbon dioxide-oxygen balance. What is Respiration in Plants. The equation for cellular respiration is as followed: 6O2 + C6H12O6 ---> 6CO2 + 6H2O + energy. Describe how the rate of photosynthesis would compare to the rate of respiration and use this to explain why the bicarbonate solution turns yellow. Experiment to demonstrate aerobic respiration: A few germinating seeds or flower-buds are put in a flask with a cork at the mouth. He really helps make science learning fun. This teaching resource introduces Cabomba, a pondweed which is much more effective than the traditional Elodea. Investigating the light factors that affect the rate of photosynthesis in Elodea Fatima Hussien Sara House, Lesha Liles, Abigail Saucedo, Melrina Stemn Biology 1441_Sec 017, Monika Pradhan; October 6, 2015 All plants rely on photosynthesis, therefore, we examined the rate at which a submerged plant such as elodea photosynthesized, with different light factors. 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. This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants. An alternative hypothesis to further evaluate the production of CO2 during cellular respiration would be, if the experiment had a longer duration of time, the dark reactions would produce more CO2 through cellular respiration causing the color of bromthymol blue to turn yellow.

In this experiment, we can see how gases produced during photosynthesis and respiration are released into the environment. A2 Biology- Effects of temperature and carbon dioxide on photosynthetic rate in Elodea. Oxygen surplus is released into the air and unused glucose stored in the plant for later use. As light intensity reduces so bubble count reduces. Plants respire all the time, day and night. 4. One common way is to gather bubbles of gas given off by an aquatic plant. As a result, no gas exchange takes place with the environment. Since these gases are lighter than water, if you shake the plant, the bubbles will quickly rise to the surface and burst. Aquatic plants undergo photosynthesis and cellular respiration much like terrestrial plants. During photosynthesis, plants are using the energy of the sun to build molecules which effectively store this energy (glucose). To demonstrate this, you will determine whether CO 2 is consumed or produced as Elodea is placed in either a dark or light environment. Without photosynthesis, we wouldn’t have oxygen or food to stay alive. In this lab, students will be testing whether or not aquatic plants do photosynthesis in the dark or light, and also testing if they do cellular respiration during the dark or light.

Photosynthesis takes place in the chloroplast and the number of leaves will affect the photosynthesis rate. Bromothymol blue is an indicator solution to those used to test for food nutrients. Bromthymol blue is used as an indicator for the presence of CO2 in solution. Photosynthesis and cellular respiration are key processes in maintaining this balance. Plants, through the process On the other hand, photosynthesis is the process where light energy is converted into chemical energy stored in glucose that can later be used in respiration. The change in CO 2 will be detected by the pH indicator phenol red. This is why plants are so important to human and other animals’ survival. Extra oxygen is released into the atmosphere. One common way is to gather bubbles of gas given off by an aquatic plant. Egeria densa, also known as Elodea densa because of its previously incorrect classification in the Elodea genus, is the most popular aquatic plant used to teach photosynthesis in the classroom. Oxygen is consumed while carbon dioxide is released in plant respiration at night. Living objects breathe because they need to obtain oxygen to carry out cellular respiration to stay alive, just like plants need to respire to stay alive. Assesses students' understanding of respiration and photosynthesis, and their … A sample of elodea is placed in a test tube, submerged in bicarbonate indicator solution. Also, if a sealed test tube containing bromthymol blue and an elodea plant in a dark environment.
To accomplish this, the plants were subjected t different light colours (Blue, Green, Red and purple). However, Cabomba is a more reliable plant and much more effective than the traditional Elodea. 4. The change in CO 2 In this experiment, we were testing the rate of photosynthesis in elodea. Originally from Brazil, E. densa has spread to temperate regions on all of the continents except Antarctica. Background: In this lab you will use an indicator called bromothymol blue (BTB) to indicate whether CO2, carbon dioxide is present. The flower or leaf may float to the top, but try to make at least part of the plant stay underwater. This colorful picture book is a great introduction to botany. The hypothesis was, while CO2 is being given off during respiration, it can be re-utilized during photosynthesis. light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis.If a multiple colored film petri dishes are place under a 50 watt lamp, then the rate of photosynthesis will be greater for those with red, blue and clear film, than those with green and black film. A plant consumes all the oxygen photosynthesis generates. It starts as a blue solution in water, and turns yellow in the presence of carbon dioxide. What observation supports this inference? The color change in the light showed complete uptake of CO2, this can be concluded because the absence of CO2 changes the beginning color (yellow) to the ending color (blue). 91 Exercise 1 – Observing Photosynthesis via CO 2 Consumption 1. Photosynthesis also uses carbon dioxide faster than respiration produces it. 1. Simple Demonstration of Photosynthesis 2. Bright sunlight – Photosynthesis uses carbon dioxide and makes oxygen faster than respiration produces carbon dioxide and consumes oxygen. Tube 3 will be the Elodea in the light. Assesses students' understanding of respiration and photosynthesis, and their … Aim: to investigate the effects of temperature and carbon dioxide on the photosynthetic rate of Elodea. It is similar to you releasing a breath underwater. After an hour, observe the plant’s surface. Terms Of Service, Understanding Photosynthesis with Max Axiom, Super Scientist, How Plants Work: The Science Behind the Amazing Things Plants Do.

For further information, consult your state’s Science Safety Handbook. The test tube is covered in black paper to prevent any light reaching the plant. Plants, through the process of photosynthesis, use energy absorbed from sunlight, water, and … Some of the experiments are: 1. After performing the experiment with several samples in each environment, the results support the hypothesis that during photosynthesis CO2 will be re-utilized, and during cellular respiration CO2 will be given off. Using What You Know About The Experiment From The Lab Exercise, Answer The Following. In this experiment I use a plant called Elodea (pond weed). 2. Do plants breathe? We have learned that photosynthesis involves the conversion of carbon dioxide and water into organic molecules such as glucose. Cover Tube 1 with tin foil (there is no Elodea in Tube 1) and place it in the test tube rack. Water used in photosynthesis. It also uses all the carbon dioxide respiration creates. Using what you know about the experiment from the lab exercise, answer the following. This test can be done with and without snails. However both ways will demonstrate how photosynthesis produces oxygen, and cellular respiration uses oxygen and create Carbon dioxide. a. Reading and following the safety precautions of all materials used in an activity is the sole responsibility of each individual. In doing so, oxygen is a product while carbon dioxide is a reactant that is used up during photosynthesis. Here is a popular science experiment to visually see how plants “breathe”. It teaches key vocabulary such as leaf, stem, root, xylem, cellulose, chloroplast, photosynthesis and respiration, and the pronunciation. What is Respiration in Plants. To demonstrate this we will determine whether CO 2 is consumed or produced as elodea (anacharis) is placed in either a light or dark environment. 3. Plants use carbon dioxide and produce oxygen gas during photosynthesis. tasks, and the student background sheet entitled “Photosynthesis and Respiration in Elodea,” they are asked to design an experiment which will allow them to demonstrate the use of CO2 by a green plant in photosynthesis, and net production of CO2 (by respiration) in the absence of photosynthetic activity. Explain why phenol red can be used to provide evidence of a plant’s carbon fixation. Dissolved oxygen can be measured directly to determine if aquatic plants undergo photosynthesis or cellular respiration in different conditions. Photosynthesis-Elodea Lab Photosynthesis is the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar. During the experiment, I learned the role of Sodium Bicarbonate and that photosynthesis can happen very quickly. They produce carbon dioxide during cellular respiration. There should be some air bubbles formed on the pedals or the leaf. This lab involves the qualitative measurement of the changes in carbon dioxide concentration associated with respiration and photosynthesis in the freshwater plant Elodea. IntroductionThis lab has been created in order to find what extent does distance from a light source (5cm, 10cm, and 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min) in Elodea water plants. But photosynthesis only occurs during the day when there is sunlight. During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing. When the plant is submerged in the water, bubbles of oxygen or carbon dioxide released are trapped and they stick on the leaves or petals temporarily. Oxygen dissolves into water when aquatic autotrophs release oxygen as a byproduct of photosynthesis. The controls being tested were two negative controls that consisted of one test tube containing bromothymol blue, CO2, and an elodea plant while being in a dark environment. Requirements: Few branches of an aquatic plant, i.e., Hydrilia, etc., beaker, glass funnel, test tube, sodium bicarbonate, etc. By Rookie Parenting Science Updated 10/29/2020. This lab involves the qualitative measurement of the changes in carbon dioxide concentration associated with respiration and photosynthesis in the freshwater plant Elodea. The results do support the hypothesis. Now the intensity of light is increased and the rate of photosynthesis is measured until again a cons­tant level is reached. As photosynthesis occurs and O2 is added back into the test tube containing the Elodea and bromthymol blue solution it will change back to the blueish tint, the test tubes placed in the dark should remain clear, or the faint yellow green. ADVERTISEMENTS: The following points highlight the top eleven experiments on photosynthesis in plants. The hypothesis was, while CO2 is being given off during respiration, it can be re-utilized during photosynthesis. Answer: Membranes function in processing energy transformation and in the organization of chemical reactions. This is Book 8 in the Super Smart Science book series. ADVERTISEMENTS: Here is a list of top ten experiments on photosynthesis with diagram. Elodea is an aquatic plant of a genus Posted on November 3, 2020. Oxygen and carbon dioxide pass in and out of the stomata in the plants through diffusion. In the test tubes that contained Elodea, where did the CO 2 go? (You can also leave it in the dark but it may take longer to see results.). a. we conducted on elodea can be set up to compare the rates of photosynthesis and cellular respiration in other conditions, like winter and spring. The results show significant differences in color change in its respective environment. Warning is hereby given that not all activities are appropriate for all individuals or in all situations. Think about the chemical equations for respiration and photosynthesis. 2. consumed or produced in a reaction. Demonstrating oxygen formation during photosynthesis can be a tricky process.
