Note: the sugar glucose produced by photosynthesis are used for two different purposes:

(1) building blocks to synthesize the molecules that make up the plant’s biomass

(2) input for cellular respiration to produce the ATP needed to provide energy for the plant’s biological processes.

1. Which process can result in increased biomass for a plant; Cell Respiration or Photosynthesis?

2. What molecule is mainly the weight of that plant?

3. Which process can result in decreased biomass for a plant; Cell Respiration or Photosynthesis?

4. Where did that weight go?
