NEET BIOLOGY

Detailed explanation-1: -The stomata helps with the exchange of gases in the leaves while root hair helps with exchange of gases in the roots.

Detailed explanation-2: -A plant’s roots absorb air from the gaps between soil particles. The air in the soil particles comes into touch with the root hairs. The oxygen in soil particles diffuses into root hair and reaches all of the root’s cells, where it is used in respiration.

Detailed explanation-3: -Root hair cells 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: -Like all other living cells of the plants, the root cells take up air from the air spaces present between the soil particles.

Detailed explanation-5: -Best Answer (b) Roots of plant have minute hair like appendages or outgrowths called root-hair. These root-hair penetrate soil and take up air from the air spaces present between the soil particles.
