Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water is also lost from plants in liquid form through the hydathode (resembles a large stoma) that is always open at the edge of the leaf at night or when the air humidity is high.Name this process.
A
Guttation
B
Transpiration
C
Centrifugation
D
Respiration
Explanation: 

Detailed explanation-1: -Guttation is the loss of water in the form of liquid through hydathodes or water stomata.

Detailed explanation-2: -The loss of water in the form of liquid through hydathodes is called guttation.

Detailed explanation-3: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.

Detailed explanation-4: -In fact, you have observed a phenomenon called “guttation”, by which plants exude water from structures called ‘hydathodes” on margins or tips of leaf blades.

Detailed explanation-5: -The loss of water in the form of droplets through hydathodes, specialized pores present on the leaf margins and the apex is known as guttation.
