Bella Brooks Slaughter Biology 350 Marking Period #3 PS and Resp. Lab Assessment 1. Explain why respiration was measured in germinating seeds in one lab while photosynthesis was measured using leaf disks in another. Why not the reverse? Respiration was measured in germinating seeds in the Pea Lab because in germinating peas there is a high rate of cell respiration as the pea is still growing and needs to consume oxygen to continue growing. Pea plant cells rely on the process of cellular respiration to supply them with the energy that they need to stay alive and grow during germination. When the pea plants are grown the cells will still remove energy from sugar via cellular respiration; however, the sugar for cellular respiration will come from the process of photosynthesis instead of the stored …show more content…

You may need to research these: a. What is the major transport polysaccharide in plants? Sucrose is the major transport polysaccharide in plants. b. What is the major storage polysaccharide in plants? Where would these storage molecules be found in abundance and how would they get there? You must elaborate on this last question! The major storage polysaccharide in plants is starch. These molecules would be found in abundance in the stroma in the plant tubers where it is found as granules. Glucose is stored mainly in the form of starch granules, in plastids like chloroplasts and amyloplasts. Plant starch starts out as glucose, but glucose is very hard for plants to store, so it is converted to starch through polymerization. Amyoplasts turn the glucose into starch and move it to the stroma, and in tubers the stroma is a place to store the food (starch), and when plants need the energy in the starch, it converts the starch back into glucose. 6. Yeast Respiration Lab a. When we tested yeast, we were testing them under aerobic conditions. What were the PRODUCTS given off by the yeast in this lab? Which of these products did we collect data
