The process of guttation takes place
Show Hint
The process of exudation of the liquid drops from the edges of leaves is known as guttation.
- when the root pressure is high and the rate of transpiration is low
- when the root pressure is low and the rate of transpiration is high
- when the root pressure equals the rate of transpiration
- when the root pressure as well as rate of transpiration are high
The Correct Option is A
Solution and Explanation
The process of exudation of the liquid drops from the edges of leaves is known as guttation. It usually occurs through stomata-like pores called hydathodes.
- Fully turgid plants remove extra water through guttation.
- It is mainly caused by root pressure (when the root pressure is high and the rate of transpiration is low, guttation takes place).
- Hydathodes are present at the tips or margins of leaves of plants growing in moist shady places (e.g., Tropaeolum).
So, the correct answer is 'When the root pressure is high and the rate of transpiration is low'.

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.
