Question

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

Answer 1

The primary raw materials required for photosynthesis are water (H₂O) and carbon dioxide (CO₂).

How plants obtain these raw materials:

1. Water: Plants absorb water from the soil through their root hairs via osmosis. This water is then transported upward from the roots to the leaves through specialized conductive vessels called xylem.
2. Carbon dioxide: Plants obtain carbon dioxide gas from the atmosphere. The gas enters the leaves through diffusion via microscopic pores called stomata, which are primarily located on the lower epidermis and regulated by guard cells.
