Plants Photosynthesize Only in the Light. Plants Respire

Question

Plants photosynthesize only in the light. Plants respire
A) in the dark only.
B) in the light only.
C) both in light and dark.
D) never-they get their ATP from photophosphorylation.
E) only when excessive light energy induces photorespiration.

Accepted Answer

Plants respire both in light and dark to produce ATP. While photosynthesis only occurs in the light, respiration is a continuous metabolic process that occurs throughout the day and night. During respiration, plants use stored energy to produce ATP, which is essential for growth and maintenance.
