Root, in botany, the part of a vascular plant that is normally underground. Its primary functions are absorption of water and dissolved minerals and conduction of these to the stem, storage of reserve foods, and anchorage of the plant.
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. [1]
Roots are the underground part of the plant body that is usually colorless. It is primarily responsible for anchoring the plant to the soil, absorption of water and minerals, and storage of reserve foods.
Roots are the first part of a plant to grow. All vascular plants have three types of root systems. Explore the root system, discover the function of roots and learn the types of roots only @ BYJU'S.
A typical plant root system shows four distinct regions or zones: 1) region of root cap, 2) region of cell division or meristematic region 3) region of elongation, and 4) region of maturation or differentiation. Each region of the root performs specific functions.
The roots of seed plants have three major functions: anchoring the plant to the soil, absorbing water and minerals and transporting them upwards, and storing the products of photosynthesis. Some roots are modified to absorb moisture and exchange gases. Most roots are underground.
Locate and identify characteristics of the primary root, lateral or secondary roots, and root hairs. Distinguish two major types of root systems and how they develop. The general perception is that roots are the parts of the plant that are found in the soil.
Roots. Plants have specialized organs that help them survive and reproduce in a great diversity of habitats. Major organs of most plants include roots, stems, and leaves. Roots are important organs in all vascular plants. Most vascular plants have two types of roots: primary roots that grow downward and secondary roots that
Root systems Peanut seed embryo. Image credit: Tom Michaels. A plant’s root originates in the embryo formed within the seed. The section of the embryo that is root tissue is called the radicle (note the spelling). At the tip or apex of the radicle is a region of rapid cell division and growth called an apical meristem (you may recall that shoots have an apical meristem too).
The roots of a plant perform a range of services that are essential to the survival of any land plant; they absorb water and nutrients from the soil, help to anchor the plant to the ground and often store large quantities of food.
