Given is the sequence of events that lead to the opening of stomata in plants during day light:Accumulated of substances X and Y in the guard cell→increase solute concentration in the guard cells→water potential of guard cells→endosmosis of water in the guard cells→ increased turgidity of the guard cells→stomata opens.The letter X, Y and Z represent:

Question

TestUstad · Accepted Answer

Glucose, Potassium ions decreases. As concentration of glucose and potassium ions increases, water potential decreases. This causes opening of stomata. So option B is correct.
