AP BIOLOGY

Detailed explanation-1: -Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

Detailed explanation-2: -What do roots do? They have three major jobs: absorbing water and minerals, anchoring and supporting the plant, and storing food. Absorbing water and minerals: Thin-walled epidermal cells and root hairs are well suited to absorb water and dissolved minerals from the soil.

Detailed explanation-3: -Absorption of water and nutrients from the soil. Conduction of absorbed water and nutrients to stem. Storage of food. Vegetative reproduction and competition with other plants.

Detailed explanation-4: -Conclusion: Important functions of roots include anchorage of the plant, absorption of water and dissolved nutrients, their conduction to the shoot, storage of nutrients, vegetative propagation, and binding of soil particles.

Detailed explanation-5: -Tree roots anchor the tree in the soil, keeping it straight and stable, and absorb water from the soil. Tree roots also take nutrients and chemicals out of the soil and use them to produce what they need for the tree’s growth, development, and repair.
