Question

Why is Photosynthesis considered as an endothermic reaction?

Answer 1

Photosynthesis is an example of an endothermic chemical reaction. In thisprocess, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. This reaction requires 15MJ of energy (sunlight) for every kilogram of glucose that is produced:

sunlight + 6CO2(g) + H2O(l) = C6H12O6(aq) + 6O2(g)

P.S: Remember, thermal means enery or heat. Endo stands for taking in or absorbing, and exo means releasing.

Answer 2

Answer :-

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.
