Question

Explain why photosynthesis is an endothermic process

Answer 1

 In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. This reaction requires 15 MJ of energy (sunlight) for every kilogram of glucose that is produced.

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.
