Question

Q. what is transpiration ? describe k+ ion theory for opening and closing of stomata?

Answer 1

Answer:

K+Ion Concentration Theory: It is a recent theory. According to this theory, the stomatal opening and closing depends on the generation of a potassium ion gradient. ATP produced in the guard cells during photosynthesis is utilised to pump the potassium ions of the adjacent cells into the guard cells.
