Question

Q.2. Why is photosynthesis considered an endothermic reaction ?​

Answer 1

Answer:

Photosynthesis is considered to be an “endothermic reaction” because it absorbs the sun's energy to enable the reaction to happen. Like most of the endothermic reactions, the plants do not absorb heat but they absorb sun's photothermal energy to perform 'photosynthesis' in order to produce starch.

Explanation:

Answer 2

Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.
