Question

If concentration of solute has decreased in guard cells, what change can be observed in it? (A) Osmotic pressure increases (B) Water potential increases (C) Water potential decreases (D) Both (b) and (c)

If the concentration of solute decreases in guard cells of stomata, the water potential will increase. This causes exosmosis, which in turn decreases the turgidity of guard cells. Thus, closing of stomata takes place.

Osmotic pressure increases

Water potential increases

Water potential decreases

Both (b) and (c)
