Which structure is responsible for the opening and closing of stomata?

Answer 1

guard cells

Answer 2

Stomatal pores close if excessive water loss occurs. As long as there is sufficient water in the soil to replace the water that is being lost by a plant, stomata stay open. Low concentrations of CO2 also cause the stomata to open

source.

The stomata's function is to allow gas exchange with the surrounding air, so that the plant can intake carbon dioxide and oxygen. Stomatal opening is favored when there is plentiful water and moderate temperatures. Abscissic acid, a plant hormone, acts on the guard cells to open and close stomata.

Some plants are even genetically engineered with a mutated era gene, which makes them more sensitive to abscissic acid and more prone to the opening and closing of guard cells.

When guard cells are full of water, they stretch away from each other and the stomata are open. When guard cells are limp, they fall on each other and the stomata are closed.

Potassium ions play a role in the opening and closing of stomata by changing the concentration of ions in the guard cells. When the potassium ions are in the guard cells, water also flows in the guard cells because of osmosis and the stomata open. When the potassium ions are out of the guard cells, water also flows out of the guard cells because of osmosis and the stomata close.

Answer 3

Structures that cause stomata to appear either open or closed are guard cells. The function of the structures called stomata that are present in leaf epidermis has exchange.

the turgidity of the guard cells ils responsible for that
