Answer: The word equation for photosynthesis is -
Carbon dioxide + Water → Glucose+ Oxygen
Photosynthesis is a process of formation of food in green plants and algae. In this process, light energy from sun is absorbed ( by chlorophyll) in the presence of carbon dioxide and water through a series of chemical reactions.
This produces chemical energy in the form of ATP and NADH. This is utilized in the formation of food, which is a carbohydrate ( glucose).
Glucose and Oxygen are produced as byproduct of the photosynthesis.
