Answer : The photosynthesis is a type of endothermic reaction.
Explanation :
Photosynthesis : It is a type of chemical reaction that occurs in the green plants or living organism.
During the photosynthesis process, the carbon dioxide reacts with water in the presence of sunlight to produce glucose and oxygen as a product.
The balanced chemical reaction will be,

In the photosynthesis reaction, carbon dioxide and water molecule are the reactants and glucose and oxygen are the products.
It is an endothermic reaction in which the energy or heat are given to the system. As we know that the photosynthesis reaction can not takes place without sunlight.
Hence, the photosynthesis is a type of endothermic reaction.
