HORTICULTURE

Detailed explanation-1: -Roots are the parts of plants responsible for water and minerals absorption. It is also involved in the anchorage of the plant.

Detailed explanation-2: -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-3: -Root hairs help plants to absorb water from the soil.

Detailed explanation-4: -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-5: -Water, sunlight, and carbon dioxide are the essential components of photosynthesis. Thus, photosynthesis is carried out only in the presence of water, which is absorbed by the roots in plants.
