explain different types of root systems and function
Answers
Answer :
Root System -
- Root is the elongation of radicle.
- The radicle mainly develops to form a primary root.
- The primary root bears lateral roots which are called as secondary roots, etc. roots.
- The main function of roots include -
- Absorption of water
- Absorption of minerals
- Storing and preserving food
- Providing anchorage to the plant
- Synthesis of plant growth regulation
- The three main types of root system includes -
- Tap root system
- Fibrous root system
- Adventitious root system
- Tap root consists of a primary roots and the lateral roots developed from the primary root. Ex - Mustard plants.
- Fibrous root includes roots that originate from the base of the stem. Ex - Grass.
- Adventitious root includes roots that arise from the other parts of plants other than the radicle. Ex - Banyan.

________________
- Roots are the important underground part of all vascular plants. This part of the plant is mainly responsible for ancho`ring it down into the ground and absorbing the essential mineral elements, nutrients, and water from the soil. It is also used to store food
- Few examples of plants with the aerial roots are–Bonsai, Banyan Tree, Mangroves, etc.
Types of Roots
TapRoot System
Taproots have a main central root upon which, small, lateral roots called root hairs are attached. Mustard, carrot, beetroot, parsley, china rose and all dicoty`ledons are examples of taproot systems.
Fibrous Root System
- Fibrous roots, on the other hand, are bushy roots in which thin, moder`ately branching roots grow from the stem. Rice, wheat, maize, marigold, banana and all monocotyledons are some examples of the fibrous root system.
Functions of Root
- Following are the important functions of root:
Roots perform various functions that are necessary for the survival of the plants. They are an integral or integr`ated system that helps the plant in:
- Anchoring: Roots are the reason plants remain attached to the ground. They support the plant body, ensuring that it stands erect.
Absorption: Primary fun`ction of the roots is to abs`orb water and dissolved minerals from the soil. This is cru`cial as it helps in the process of photosynthesis.
- Storage: Plants prepare food and store in the form of starch in the leaves, shoots and roots. Prominent examples include carrots, radish, beetroot, etc.
Reproduction: Even though roots are not the reproductive part of plants, they are vegetative parts. In some plants, the roots are a means of reproduction. For ins`tance, new plants arise from creeping horizontal stems called runners (stolons) in jasmine, grass, etc. This type of reproduction is called vegetative propa`gation.
- Ecological Function: They check soil erosion, provide sustenance and also habitat to various organisms.
