Question

What is the function of roots in plants?

Answer 1

Roots:

1. The root is generally an underground part of the plant.
2. They are positively geotropic and negatively phototropic.
3. A root cap, a zone of division, an elongation zone, and a zone of maturation are the four regions of a root.
4. On the basis of origin the roots can be classified into - Tap root system, fibrous root system, and adventitious root system.
5. Tap root system - It is made up of the primary roots and their branches. For example - dicots (mustards).
6. Fibrous root system - The primary root is transient and is typically replaced by a number of small fibrous roots. These roots come from the stem's base. For example - monocots ( wheat).
7. Adventitious root system -Any part of the plant, besides the radicle, has the ability to create these roots. For example - grasses

The function of root:

1. Providing a proper anchorage to the plant parts.
2. Water and dissolved mineral absorption and transmission to the stem.
3. Reserve food storage.
4. Synthesis of plant growth regulators.
