Question

Which of the following theories gives the latest
explanation for closure of stomata?
(a) Starch glucose theory
(b) Munch theory
(c) ABA theory
(d) Active K⁺ transport theory

Answer 1

Answer:

Option 4: Active K+ transport theory

Answer 2

The latest explanation for the closure of stomata was given by the active potassium ion $\bold{(K^{+})}$ transport theory.

Option: (d)

Explanation:

• There has been many theories which had been proposed for the opening and closing of the stomata.

• One of such theory is active potassium ion transport theory. According to this theory when potassium ion enters the guard cell ID draws in water due to osmosis and hence the guard cell opens.

• This happens after photosynthesis was sufficient amount of glucose and Mallet is formed.

• The reverse happens during the closure of the stomata.
