• 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. Root hair cells are adapted for this by having a large 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.
