Question

By which method, is water absorbed by root hairs?

(A) Transfer

(B) Diffusion

(C) Osmosis

(D) Both (A) and (B)

Answer 1

Correct option is: (C) Osmosis

Water passes from the soil to the root hair cell's cytoplasm by osmosis. This happens because the water in the soil has a higher water potential than the root hair cell cytoplasm. Root hair cells have a large surface area for absorption of water and to speed up osmosis.
