list two materials necessary during photosynthesis

Answer 1

Two essential materials necessary for photosynthesis are:

1. Carbon Dioxide (CO₂) - This gas is absorbed from the atmosphere through the stomata in plant leaves.
2. Water (H₂O) - This is taken up by the roots from the soil and transported to the leaves.

These materials, along with sunlight, are crucial for the process of photosynthesis, where plants convert them into glucose and oxygen.
