What is the name for the opening and closing cells on the underside of plant leaves?
The opening and closing cells on the underside of plant leaves are called stomata. These small pores are surrounded by guard cells, which regulate their opening and closing to control gas exchange, allowing carbon dioxide in for photosynthesis and oxygen out, while also managing water loss through transpiration.
What cells control the opening and closing of these holes?
The cells that control the opening and closing of holes, such as pores in biological membranes, are typically known as guard cells in plants or specialized muscle cells in animals. Guard cells regulate the opening and closing of stomata, which are pores on the leaf surface, to facilitate gas exchange and water regulation. In animals, smooth muscle cells can control the diameter of blood vessels or the openings of various organs. These cells respond to various signals, including environmental factors and hormonal changes, to manage the flow of substances through the holes.
Each stoma is composed of?
Each stoma is composed of two specialized cells called guard cells that control the opening and closing of the pore. This structure allows for gas exchange, such as the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor.
What is the function of a vacuole in a Guard Cell?
Vacuoles in guard cells help regulate the movement of water and ions in and out of the cell, which in turn affects the opening and closing of the stomata. The vacuole can change its volume to control the turgidity of the guard cell, leading to the opening and closing of the stomatal pore for gas exchange.
What leaf structure adjusts the size of the stomata?
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.
What is the of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
What the function of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
Guard cells control the opening and closing of the stomates true or false?
true :)
What ions involve the opening and closing of stomata?
Potassium ions, they contribute to the control of turgidity of guard cells, and thus the opening and closing of stomata.
What does guard cells do on a leaf?
Guard cells on a leaf regulate the opening and closing of stomata, which are small pores that control gas exchange and water loss in plants. By changing shape, guard cells control the size of the stomatal pore to balance the needs of photosynthesis with the need to conserve water.

What cells guard the opening and closing of the stomata?
The guard cells are specialized cells that control the opening and closing of the stomata in plant leaves. They can change shape to regulate the exchange of gases and water vapor between the leaf and the surrounding environment.
Each stoma is composed of?
Each stoma is composed of two specialized cells called guard cells that control the opening and closing of the pore. This structure allows for gas exchange, such as the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor.
The type of cell that controls the opening and closing of stomata is called?
guard cells
What is the function of a vacuole in a Guard Cell?
Vacuoles in guard cells help regulate the movement of water and ions in and out of the cell, which in turn affects the opening and closing of the stomata. The vacuole can change its volume to control the turgidity of the guard cell, leading to the opening and closing of the stomatal pore for gas exchange.
Are guard cells part of the stomata or does stomata only refer to the pore on the lower surface of the leaf?
The stomata are the pores and the guard cells control the opening and closing of these pores.
