Question

The two main processes by which plant cells absorb, release, and use energy are

A) fermentation and respiration.
B) digestion and photosynthesis.
C) photosynthesis and respiration.
D) aerobic and anaerobic respiration.

Answer 1

Plant cells do not perform respiration, so A,C, and D couldn't be correct but they don't digest either. so gain energy plants go through a light dependent reaction and the Calvin cycle which makes up photosynthesis. 

Answer 2

Photosynthesis and respiration because they make glucose during when the sun is present and use glucose at night
