what would happen to photosynthesis if all of the three carbon sugars produced in Calvin cycle were used to make organic compounds?
Explain how a global temperature increase could affect plants?
explain how the world would be different if C4 plants and CAM plants had not evolved?

one three carbon sugar is needed to help the cycle restart.

1. The Calvin cycle could not continue to be a cycle. Some of the three-carbon compounds are shuttled off to build glucose, but some of them have to be sent along to continue the cycle. Carbon dioxide has to be added to SOMETHING when it enters the cycle.
2. Temp. increase would increase water loss through transpiration. Plants might not be able to maintain homeostasis in relation to water under those conditions.
