Which nutrient helps in stomata opening and closing?

Which nutrient helps in stomata opening and closing? Correct Answer Potassium

The correct answer is Potassium.

Key Points

• An important function of potassium channels is mediating long-term potassium transport during cell movements, turgor changes, and tropisms.
• Two guard cells surround each stomatal pore in leaves and control the opening and closing of their central pore.
• It is done via increases in their solute content during stomatal opening and decreases in solute content during stomatal closing.
• Potassium (K+out) channels in guard cells contribute to stomatal closing in leaves.
• Guard cells accumulate potassium (K+), which results in stomatal opening and release K+, which results in stomatal closing.
