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 are the tiny pore like structures called on the underside of leaves that are used for gas exchange?
The tiny pore-like structures on the underside of leaves that facilitate gas exchange are called stomata. These openings allow carbon dioxide to enter the leaf for photosynthesis while enabling oxygen and water vapor to exit. Stomata are surrounded by specialized cells known as guard cells, which regulate their opening and closing based on environmental conditions.
Are chloroplast present in guard cells?
Yes, chloroplasts are present in guard cells. Guard cells are specialized cells found in the epidermis of plant leaves and stems that regulate the opening and closing of stomata. Chloroplasts, which contain the green pigment chlorophyll, are responsible for photosynthesis and are necessary for the energy production needed for the opening and closing of stomata.
What is the cell that conrols the gases going into and leaving a leaf?
Plants have pores on the underside of the leave called stomata (or stoma in singular). By opening or closing these pores, they allow the oxygen formed inside the plant to exit, and the carbon dioxide outside to enter.
The guard cells control the opening and closing of what structure?
The guard cells control the opening and closing of the stomata, which are tiny pores found on the surface of plant leaves that regulate gas exchange and water loss. By adjusting the turgor pressure within the guard cells, the stomata open to allow gases like oxygen and carbon dioxide to enter and exit the leaf.
On which layer of epidermis are guard cells found?
Guard cells are found on the epidermis of plant leaves, specifically within the lower epidermis. These specialized cells control the opening and closing of stomata to regulate gas exchange and water loss in the plant.
What structure prevents water from escaping a plant's leaves?
Cuticle
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.
The type of cell that controls the opening and closing of stomata is called?
guard cells
What do guard cells in a plant do?
The guard cells in a plant are responsible for opening and closing the stomata. The stomata is a tiny opening on the blade of a leaf that allows for carbon dioxide to enter and water + oxygen to be released. The guard cells are triggered by concentrations of potassium ions.
Are chloroplast present in guard cells?
Yes, chloroplasts are present in guard cells. Guard cells are specialized cells found in the epidermis of plant leaves and stems that regulate the opening and closing of stomata. Chloroplasts, which contain the green pigment chlorophyll, are responsible for photosynthesis and are necessary for the energy production needed for the opening and closing of stomata.
Are guard cells alive or dead?
Guard cells are alive. They are specialized cells found in the epidermis of plant leaves that control the opening and closing of stomata to regulate gas exchange and water loss.
What is the opening in a leaf that allows for carbon dioxide to come in and oxygen to leave?
The opening in a leaf that allows for gas exchange is called a stoma (plural: stomata). Stomata are typically located on the underside of the leaf and are bordered by guard cells that regulate their opening and closing to control gas exchange.
Is the specialized structure that surrounds the stomata on the underside of leaves?
guard cells
What is the of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
What is the cell that conrols the gases going into and leaving a leaf?
Plants have pores on the underside of the leave called stomata (or stoma in singular). By opening or closing these pores, they allow the oxygen formed inside the plant to exit, and the carbon dioxide outside to enter.
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 the guard do?
Gaurd cells help in opening and closing of stomata
