Step 1
Photosynthesis is endothermic taking in energy and aerobic respiration is exothermic.
Answer
This statement is correct. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen, absorbing energy in the process. Hence, it is considered endothermic. In contrast, aerobic respiration occurs continuously in plant cells even during the night, releasing energy from glucose and utilizing oxygen, making it exothermic.
