Quizplus · Accepted Answer

Potassium plays a crucial role in regulating the opening and closing of stomata (pores) in leaves by controlling the turgor pressure of guard cells. This helps to regulate gas exchange and water loss in plants. Calcium, copper, phosphorus, and iron are also essential plant nutrients but do not directly regulate stomatal function.
