Question

Why is photosynthesis important?

Answer 1

Photosynthesis is important for survival of living organisms as it synthesizes carbohydrates from raw materials like `CO2 and H2O`, that is source of energy for plants and animals.

Explanation:

Photosynthesis is most important process by green plants in which carbohydrates are synthesized from substances like `CO2 and H2O` in presence of light.

It converts solar energy into chemical energy that is stored in glucose molecules from which complex carbohydrates are synthesized.

Carbohydrates produced in photosynthesis are substrate for cellular respiration for all living organisms.

The carbohydrates used as respiratory substrate by animals are also the product of photosynthesis as they feed on plants.

All plant products used by humans like wood, fibers, fruits , vegetables and medicines are the product of photosynthesis.

Photosynthesis is not only source of energy for the living world but is vital for the existence of all organisms as `O2` is liberated during photosynthesis, which is necessary for cellular respiration.
