Given off during respiration, it can be re-utilized during photosynthesis) in this lab, you will try to demonstrate the net change in carbon dioxide when the common fresh water plant elodea is placed under different conditions. Class practical 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 lesson organisation the work could be carried out individually or in groups of up to 3 students (counter, timekeeper and scribe. In the second half of photosynthesis, the light independent reactions, carbon is fixed: co2 is the input, while a biologically useful form of stored energy, c 6 h 12 o 6 is the output however. Elodea experiment aim to find out if temperature affects the rate of photosynthesis in elodea apparatus heat mat, gauze, bunsen burner, tripod, beaker. Materials: teacher pages hypothesis: brine shrimp (animals) and elodea (plants) will change the levels of carbon dioxide (co₂) and dissolved oxygen (do) values within the water sample under light and dark environmental conditions which will result in the.
Investigating the effect of co2 concentrationon the rate of photosynthesis in elodea investigating the effect of co2 concentrationon the rate of photosynthesis in elodea photosynthesis lab. Lab 13: estimating rates of photosynthesis bsc 1007 introduction to biology learning objectives upon completion of this lab you will be able to: estimate the rate of photosynthesis for the aquatic plant elodea by measuring oxygen production determine the effect that light color has on photosynthetic rate. In this lab, we will examine some factors which influence net photosynthesis note in equation 1 that co 2 is consumed in photosynthesis, the carbon is then immobilized or fixed into a higher molecular weight compound, and the oxygen is released.
A plant uses carbon, along with water and light, during photosynthesis, to create food for itself in the form of glucose carbon fixation means that carbon dioxide, in a gaseous form, is used as the input to output glucose, a solid compound and a biologically useful form of stored energy. Discovering photosynthesis by experiments 1 discovering photosynthesis by experiments (ie, its colour) on the rate of photosynthesis on elodea canadensis the rate of photosynthesis is defined by the rate of oxygen of green plant tissues light, carbon dioxide, temperature, water supply and availability to minerals are the most. Lab exam 2 shared flashcard set details title lab exam 2 description exercise 12, 13, 16 total cards 92 because the fish would have given off carbon dioxide while the plant would have used the carbon dioxide in the procedure observing the uptake of co₂ during photosynthesis, you added _____ to a test tube with your breath.
This activity demonstrates the uptake of carbon dioxide by plants, using elodeaas the example elodea is a pond plant that lives below the water surface and thus extracts dissolved carbon dioxide from the water rather than directly from the atmosphere as terrestrial plants do. There are 2 things we can quickly measure in this experiment (the dependent variables): amount of oxygen produced, or, amount of carbon dioxide used if the rate of photosynthesis increases, the rate of oxygen production goes up, and the rate of co 2 consumption rises too. Light, carbon dioxide and photosynthesis lab welcome to the second on-line lab in this lab you will investigate the relationship between light absorption and carbon dioxide intake during the process of photosynthesis break the elodea into 10, one inch pieces 3 place one piece of eldea into each test tube. Because, like terrestrial plants, they need sunlight for photosynthesis one of the requirements for photosynthesis is co 2 carbon dioxide dissolves in water making it acidic the increase in ph as an indication of dissolved co 2 uptake by the plants we will use two kinds of plants: the freshwater aquarium plant, cabomba and the. Lab report chemical equation: the chemical equation for photosynthesis is: hypothesis elodea stems were cut at an angle and the ends of the stems were crushed using fingers the color changes helped to better explain the use of carbon dioxide during photosynthesis.
Photosynthesis in elodea in an intact plant, both electron transport and carbon fixation will continue as long as the plant is illuminated, and it is possible to study the effect of light intensity and the concentration of co 2 on the rate. Procedure 134 observe co2 uptake during photosynthesis fill two test tube with phenol red diluted use straw to blow into the test tubes place elodea leaf cover the tubes and then place under the light. Elodea photosynthesis lab science project the less acidic and more blue the bromothymol blue solution becomes as the plant uses carbon dioxide during photosynthesisthe less photosynthetic activity, the more acidic and yellow the bromothymol blue solution becomes as the plant produces carbon dioxide during cellular respiration elodea, an.
The rate of photosynthesis can be determined by measuring the rate of production of sugar or oxygen or by measuring the rate of decrease in carbon dioxide concentration a common aquarium plant called, elodea , can be used to show fast carbon dioxide is being removed from the water in which the elodea is submerged. In this lab, you will use phenol red as an indicator to show whether co2 is being consumed or produced in a reaction within plants lab is set up by placing elodea plants in test tubes with a solution of phenol red a change in color occurs as carbon dioxide is consumed. The use of co2 by elodea during photosynthesis, photosynthesis or respiration a post-lab class discussion would include the sharing of information between the two groups 2 address “purpose a” and “purpose b” sequentially as two separate activities a follow-up during photosynthesis, co2 is consumed by plants 5 respiration. Carbon dioxide is a reactant that is used up during photosynthesis in the first experiment, we will be using the same plant you examined in lab 3 called elodea.
