Use your knowledge of photosynthesis and cellular respiration to complete the

above equations.

Break into your lab groups and follow the directions on the cards

at your lab table.

Cellular Respiration is the cellular process responsible for the color change from blue to yellow in Tube S-3.

The other tubes did not change color because the plants are going through photosynthesis.

Cellular Respiration is the cellular process responsible for the color change.

CO2 is the reactant responsible for the color change.

Both animals and plants go through the process of of cellular respiration. In the first test tube in the presence of sunlight, the plant is able to photosynthesize and produce enough oxygen to prevent the formation of carbonic acid. In the second test tube there is no light energy to power photosynthesis. Both the plant and the snail are going through cellular respiration resulting in the formation of carbonic acid.

Create a Venn diagram like the

one on the right in your notebook

using the above terms and phrases.

Everyone needs to get a Holt biology textbook and two copies of the leaf

and arrow diagrams and then break into equal

lab groups.

Use the foldable instructions on your lab table along with the information on

pages 97-103 of your textbook to

complete the activity
