• A. Roots are the major sites for water absorption in plants.
• B. The base of the stem is specialized to absorb water and minerals.
• C. Water enters the stem through diffusion
• D. None of these

Answer 1

The correct option is A

Roots are the major sites for water absorption in plants.

Plants absorb water from the soil by osmosis. Roots of plants have hair like structures called root hairs, these hairs increase the surface area to speed up osmosis. The absorbed water is transported through the roots to the rest of the plant where it is used for different purposes like for photosynthesis, transpiration etc.
