The guard cells.
Guard cells are the specialized cells that monitor and regulate the size of stomata in plant leaves. They control the opening and closing of stomata to regulate gas exchange and water loss in the plant.
Guard Cells
It is also called irregular celled type stomata. this type of stomata remains surrounded by a limited number of cells which cannot be distinguished from other epidermal cells. Thus the subsidery cells are absent. This also called ranunculous type and commonly found im families like Ranunculaceae, Cappariaceae and others.
Guard cells, which are specialized cells that surround the stomata, are responsible for adjusting the size of the stomatal pore. When the guard cells take up or release water, they change shape and control the opening and closing of the stomata.
Guard cells control the opening and closing of stomata, tiny pores on the surface of leaves that regulate gas exchange (such as oxygen and carbon dioxide) and water loss in plants. When the guard cells take in water, they swell and the stomata open; when they lose water, they shrink and the stomata close.
I suppose it is because the cells multiply, not just grow, so some plants that need more regulating just adapt by multiplying their cells, not enlarging them.
Guard cells control the size of openings called stomata on the surface of leaves. When the guard cells take up water, they swell and cause the stomata to open, allowing carbon dioxide to enter for photosynthesis. When they lose water, the guard cells shrink and the stomata close to prevent excessive water loss.
Guard Cells surround the stomata, and enable it to open or shut.
The stomata are controlled by two epidermal cells called guard cells. When water flows in, the guard cells swell up and closes the stomata. When the water leaves, it becomes flaccid and opens the stomata.
Guard cells are specialized cells in the epidermis of leaves that control the size of stomata. They are responsible for regulating the opening and closing of the stomatal pores to allow gas exchange and regulate water loss.
Epidermal cells surround the stomata.
Guard cells. They are bean-shaped and this allows for the opening and closing of stomata.
