NEET BIOLOGY

Detailed explanation-1: -Root hairs greatly increase the root surface area and therefore increase the ability of a plant to absorb water and nutrients.

Detailed explanation-2: -Complete answer Root hairs are the structures which increase the surface area of absorption of water and minerals.

Detailed explanation-3: -Figure 2: Root hairs often form on fine roots and improve water absorption by increasing root surface area and by improving contact with the soil.

Detailed explanation-4: -The absorption of water and minerals is the function of the root hairs that are present at the maturation region.

Detailed explanation-5: -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. This kind of absorption takes place passively. The water can easily move from the region of higher concentration to the low concentration without expenditure of energy.
