Detailed Solution

The above statement is true.
It is a chemical reaction where the reactants absorb heat energy from the surrounding substance to form a product. It is called an endothermic reaction. It causes a fall in temperature. For example: when nitrogen and oxygen are heated to a temperature of about 3000°C, nitric oxide gas is formed.
Photosynthesis is an endothermic reaction because, during the method of photosynthesis, energy from the sun or sunlight is absorbed. Any chemical reaction that absorbs heat energy from the environment to form the products is termed as endothermic reaction. Photosynthesis is an endothermic reaction. This suggests it can’t occur without energy (from the sun). The sunlight required is absorbed by a green pigment called chlorophyll within the leaves.
