What do plants need for photosynthesis?

Plants need four main things for photosynthesis:

1. Sunlight – It provides the energy needed to drive the chemical reactions.
2. Carbon dioxide (CO₂) – Plants take it from the air through tiny openings in their leaves called stomata.
3. Water (H₂O)– Plants absorb it from the soil through their roots.
4. Chlorophyll – This green pigment, found in chloroplasts, captures the sunlight and helps convert carbon dioxide and water into food.
