Photosynthesis is a process by which green plants synthesize nutrients from carbon dioxide and water in the presence of sunlight. It involves the green pigment – chlorophyll, producing oxygen as a by-product.
The raw materials for photosynthesis are as follows:
- Carbon dioxide – through gaseous exchange carried out by stomata
- Water – roots absorb water from the soil provided by irrigation or even rains
- Sunlight – chlorophyll, the green pigment present in green plants traps solar energy
