Detailed explanation-1: -The plants absorb water from the soil with the help of root hair through osmosis. The diffusion of water molecules through a semi-permeable membrane is called osmosis. Root hair absorbs water from soil through osmosis. Water will be absorbed by root hairs by osmosis as the environment in the soil is hypotonic.

Detailed explanation-2: -Water from the soil is absorbed by the roots through a process known as osmosis.

Detailed explanation-3: -Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

Detailed explanation-4: -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: It is a reactant used in photosynthesis.

Detailed explanation-5: -Plants are able to absorb water and mineral ions from the soil through the process of osmosis. Just behind the growing tips of roots are thousands of tiny root hairs. These tiny root hairs increase the surface area of the root epidermis and are the main area of osmosis.
