Select the correct events leading to the opening of the stomata. I.Decline in guard cell solutes.
II.Lowering of osmotic potential of guard cells. III.Rise in potassium levels in guard cells.
IV.Movement of water from neighbouring cells into guard cells. V.Guard cells becoming flaccid
II.Lowering of osmotic potential of guard cells. III.Rise in potassium levels in guard cells.
IV.Movement of water from neighbouring cells into guard cells. V.Guard cells becoming flaccid
View answer and explanation
Correct option: B
II, III and IV
Option B is correct because the opening of stomata involves a decrease in osmotic potential, an increase in potassium levels, and the movement of water into the guard cells.
