order to maintain life.
Answer:
False
(It occurs in all living organisms.)

, Question:
What is one of the main functions of light reactions?

Question:
True or False: Dark reactions can occur in the presence or absence of light.
Answer:
True.
The term 'dark reactions' (also known as the Calvin Cycle) simply denotes the
second stage in photosynthesis—dark reactions do not actually require
darkness in order to occur.
Question:
