- turgor pressure
- osmotic pressure
- suction pressure
- root pressure
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Osmosis is the movement of water or solvent from a solution of its higher concentration (dilute solution) to a solution of its lower concentration (concentrated solution). The concentration of water in soil is higher and in root hairs is lower. So water
will move from soil to root hairs on account of osmotic pressure.

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.
