In the first experiment, we will be using the same plant you examined in Lab 3 called Elodea. The experimental set-up involves a qualitative measurement of the CO 2 concentration in the vials. The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO 2.

In this lab activity you will observe the effects of osmosis on plant cells. In the first part, you will use the weight of pieces of potato to see how much water moves in and out of cells in different salt solutions. In the second part, you will observe plasmolysis in an aquatic plant, Elodea. Materials (for each group) Part 1 …

Your lab group is asked to design, execute, and analyze an experiment that tries to accomplish the following two tasks: Task A. Demonstrate that environmental CO2 is used during photosynthesis in Elodea. Task B. Demonstrate that there is a net production of CO2 when Elodea respires in the absence of photosynthesis. Supplies and Equipment Available:

Elodea Lab This lab is designed to show how photosynthesis takes place in the aquatic plant Elodea. Because the leaves of Elodea are only a few cells thick, they will be easy to observe under the microscope to look at cells and cell parts. Materials: Sprig of Elodea Distilled Water w /Baking Soda Test Tube or clear glass Timer or Watch

Anacharis (Elodea): This fresh water plant is usually available year round at most tropical fish and pet stores. Obtain the Elodea a few days in advance of the lab and enhance growth with an artificial light source to ensure active sprigs. Elodea responds best when placed in non-chlorinated H20 with an aerator.

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. Bromothymol blue is an indicator solution to those used to test for food nutrients. It starts as a blue solution in water, and turns yellow in the presence of carbon dioxide.
