Explanation:
Detailed explanation-1: -Potassium ion plays an important role in opening and closing of stomata.
Detailed explanation-2: -To put it simply, potassium regulates the opening and closing of plant stomata. Stomates are the pores on plant leaves that allow for gas and water vapor exchange. When plants have adequate potassium, the guard cells swell and allow for complete closure of the stoma opening.
Detailed explanation-3: -Guard cells accumulate potassium (K+), which results in stomatal opening (2) and release K+, which results in stomatal closing (3).
