What is the function of the root of plants?

Answer 1

Root hairs are extremely important in water and nutrient uptake. Root hairs are ephemeral (shortlived) structures that have a high pay-off for the plant. The plant does not have to waste a lot of energy on producing them, but because of their high surface area they come in contact with a large volume of soil and therefore have a greater chance of accessing soil nutrients.

Answer 2

The functions of plant roots are:

Anchorage. The roots anchor the plant in place and prevent it from moving, being blown over or washed away by water.

Absorption of water and dissolved nutrients from the soil. Root hairs increase the surface area of the roots system as a whole and enable it to absorb large amounts of water from the soil.

Absorption of oxygen. Most of the oxygen required by the plant is actually absorbed from the soil and not directly from the atmosphere via the leaves and stoma. A lack of oxygen in the soil can cause the root system to degenerate and die - and the plant along with it. When plants are over-watered, the water replaces the pore spaces in the soil, creating anaerobic conditions, stunting or killing the plant.

Storage. Certain types of plants have roots which perform an additional function of storage (both water and food), for example the potato, yam, beetroot and Protoasparagus.

Roots also provide home or host sites for bacteria and fungi which can assist in the breakdown and assimilation of nutrients from the soil. For example nitrogen fixing bacteria which are found in the root nodules of most legumes. Grows to be a good flower
In general, a plants roots anchors the plants firmly to the ground. Then, nutrients, trace elements and water is absorbed through the roots to feed the plants.
to absorb water and nutrients needed by the plant.

Answer 3

The primary function of plant roots is absorption of water and minerals from the soil. Most of plant roots anchor the plant in place. In some cases aerial roots help plants to absorb water from the air (in case of many species of Ficus) and also help in climbing (as in case of Smilax). In sweet potato roots function is also storage of food material.

they anchor the soil.they carry water and minerals to the shoot.
