AP BIOLOGY

Detailed explanation-1: -The roots’ functions are to absorb nutrients and moisture, anchor the plant in the soil, support the stem and store food. Roots are often overlooked, probably because they are less visible than the rest of the plant.

Detailed explanation-2: -Plants absorb nutrients and water from soil through their roots.

Detailed explanation-3: -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.

Detailed explanation-4: -But, roots play a critical role in the life of a plant. They anchor the plant to support the shoots above. They absorb water and mineral nutrients and conduct them upwards. They store carbohydrates and other nutrients that are a source of energy for biennials and perennials as they awaken and grow in spring.
