What are the raw materials for photosynthesis?

The main raw materials for photosynthesis are:

1. Carbon Dioxide (CO₂):
   Plants take carbon dioxide from the air through small pores called stomata present in their leaves. It is one of the key ingredients that helps in the preparation of food.

2. Water (H₂O):
   Plants absorb water from the soil through their roots. Water is transported to the leaves through tiny tubes called xylem vessels.

3. Sunlight:
   Sunlight provides the energy required to carry out the photosynthesis process. Plants capture sunlight using a green pigment called chlorophyll present in their leaves.

4. Chlorophyll (not a raw material but essential):
   Chlorophyll is not consumed in photosynthesis but it is crucial as it traps the sunlight energy.

Explanation:

During photosynthesis, plants use carbon dioxide from the atmosphere and water from the soil in the presence of sunlight and chlorophyll to make glucose (food) and release oxygen. The chemical equation for photosynthesis is:

6CO₂ + 6H₂O → (sunlight, chlorophyll) → C₆H₁₂O₆ + 6O₂

This process allows plants to produce their own food and also releases oxygen, which is essential for life on Earth.
