Question

(a) Name the raw materials required for photosynthesis. How do plants obtain these raw materials?

Answer 1

The raw materials required for photosynthesis are carbon dioxide and water.

• The green plants take carbon dioxide from the air for photosynthesis. The carbon dioxide gas enters the leaves of the plant through the stomata present on their surface.
• The water required is absorbed by the roots of the plants from the soil through the process of osmosis.
  Carbon dioxide + Water $\underset{Chlorophyll}{\overset{Sunlight}{\to }}$ Glucose + Oxygen
