NEET BIOLOGY

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. The cell membrane of the root hair cells acts as a semi-permeable membrane. The cell sap inside the vacuole is a strong solution with low water concentration.

Detailed explanation-3: -Root hairs help plants to absorb water from the soil.

Detailed explanation-4: -The bulk of water uptake by most plants is via the roots. That said, high humidity does decrease the rate at which water is lost from the plant, and so will decrease the uptake of water from the soil.

Detailed explanation-5: -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.
