Short Note on Photosynthesis
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.
- 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.
