Potassium ions play a critical role in the opening and closing of stomata.
Stomata, an open pore, is an imperative cell structure in plant cells that is found in the stems, epidermis of leaves, and other parts of plants. Stomata are bordered by guard cells that are responsible for the opening and closing of stomata.
These organelles are vital structures that allow for the trading of water and carbon dioxide between plants and the surrounding atmosphere.
Potassium ions have a major role to play in this. The opening and closing of the stomata are influenced by adequate potassium.
More supply of potassium ions will make guard cells hypertonic allowing for more water to enter inside the cell.
