Short Note on Photosynthesis

Photosynthesis

Definition:

Photosynthesis is an autotrophic mode of nutrition which is generally a physico-chemical process by which plants can convert light energy into chemical energy, in the form of carbohydrate from simple inorganic substances like atmospheric carbon dioxide and water.

Difference between Potosynthesis and Respiration — Photosynthesis – Formula

The basic raw materials required for photosynthesis are carbon dioxide, water, chlorophyll and sunlight.
Leaves are referred to as the sites of photosynthesis. Hence, they are called as food factories of the plant.
Leaves contain small pores called stomata on both their surfaces.
Stomata are the structures which help in the exchange of gasses.
Opening and closing of the stomata occurs by the guard cells present in them.
Also, leaves are rich in green color plastids referred to as chloroplasts which are rich in chlorophyll pigment. Chlorophyll is responsible for trapping the energy from sunlight.
All this combined with sunlight and carbon dioxide, makes food.
