Document Summary
Lab exercise 5 water movement & respiration. Plant cells rely upon water to provide support by maintaining turgid internal structure. You will explore the movement of water through plant cells. Cellular respiration is a key physiological process essential to life which breaks down glucose molecules producing atp and releasing carbon dioxide and water. Your ta will distribute the containers of brassica rapa seedlings that you started in lab last week. One container will be the control receiving water and the other container will be the treated receiving 10% sodium chloride (salt, nacl). Add the 10% sodium chloride into one seedling container and add a comparable amount of pure water to the other container. Note the time in which you added the solutions and observe for the next 30 minutes: take a picture showing the control (water) and treated (10% nacl) seedlings after treatment. Insert your picture below. (10: has water moved into or out of the treated seedlings? (1)
