Consider the following statements regarding the root system of angiosperms.
I.$\quad$ In monocots, the fibrous root system arises from the base of the$\quad$$\quad$ stem.
II.$\quad$ The region of elongation is called the root hair region.
III.$\quad$ In sweet potato, the adventitious roots get swollen and store $\quad$$\quad$food.
IV. $\quad$The stems of maize and sugarcane have supportingroots called$\quad$$\quad$ prop roots.
- I and II are correct but III and IV are wrong.
- II and III are correct but I and IV are wrong.
- II and IV are correct but I and III are wrong.
- I and III are correct but II and IV are wrong.
The Correct Option is D

Top Questions on The Root
- Who coined the term 'root pressure theory'?
- When a stem of a plant is cut a few inches above the soil and xylem sap is seen flowing out through the cut end, this exudation is considered evidence for the existence of root pressure. Who proposed the theory of root pressure?
- In which plants oxygen is absorbed through aerial roots?

Concepts Used:
Root
A Root refers to the vascular part of any plant which is pinpointed or discovered at the lowest level and is entirely responsible for connecting the plant with the soil. It absorbs water (H20), minerals, nutrients, etc., and further feeds the plant for its development. Roots are also responsible for acting as the repository for food and nutrients of the plant.

Characteristics of Roots:
- Roots are homogeneous in nature due to their potential to work towards producing similar organs like secondary or tertiary roots from the pericycle.
- Roots can be examined as positively Geotropic and Hydrotropic but negatively Phototropic.
Functions of Roots:
- The roots are in charge of providing a systematic connection to the different parts of the plant.
- It is also accountable for the storage of the reserved food material and the synthesis for the growth of the plant.
