1.	Question : What is the importance of potassium in the opening and closing of stomata?
Answer» Solution :Accumulation of K in guard cells in light increases the asmotic potential of the guard cells, this causes opening of stoma. In DARK, K moves out of the guard cells and their OSMOTIC potential becomes less negative. THUS water OSMOSES out of the guard cells and their turgidity decreases. This causes stomatal closure.
