The movement of gases in and out of the leaf is regulated by what?
The movement of gases in and out of the leaf is regulated by small openings on the surface called stomata. Stomata open and close to control the exchange of carbon dioxide and oxygen during photosynthesis and respiration. The opening and closing of stomata is influenced by factors such as light intensity, humidity, and levels of carbon dioxide in the atmosphere.
What are the cells that surround the stomata called?
The cells that surround the stomata are called guard cells. They regulate the opening and closing of the stomata to control gas exchange and water loss in plants.
What are stomata in biological terms?
Stomata are small pores found on the surface of plant leaves and stems that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen and water vapor. They are surrounded by guard cells that control the opening and closing of the stomatal pore to regulate gas exchange and water loss.
How does a plant stomata work?
Stomata are tiny openings on the surface of leaves that regulate gas exchange in plants. They open to allow carbon dioxide to enter for photosynthesis and release oxygen, but close to prevent excessive water loss through transpiration. Stomata are surrounded by guard cells that control their opening and closing based on environmental cues like light intensity and moisture levels.
Where does gas exchange and water loss occur in plants?
Gas exchange occurs in the stomata, which are tiny openings on the leaves of plants. Water loss, also known as transpiration, occurs through the same stomata during the process of exchanging gases.
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.

Stomata open and close to control the exchange of carbon dioxide and oxygen during photosynthesis and respiration. The opening and closing of stomata is influenced by factors such as light intensity, humidity, and levels of carbon dioxide in the atmosphere.
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.
The type of cell that controls the opening and closing of stomata is called?
guard cells
What structural feature allows co2 from the air to enter the leaf?
Small openings on the underside of the leaf called stomata allow CO2 to enter and O2 to exit during photosynthesis. Each stoma is surrounded by guard cells that control its opening and closing to regulate gas exchange.
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 are the openings in the epidermis of a plant that allow air and water to pass in and out of the leaf?
The openings in the epidermis of a plant are called stomata. Stomata are surrounded by specialized cells called guard cells that regulate the opening and closing of the stomatal pore to control gas exchange and water loss in the leaf.
What does the guard do?
Gaurd cells help in opening and closing of stomata
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.
What are the cells that surround the stomata called?
The cells that surround the stomata are called guard cells. They regulate the opening and closing of the stomata to control gas exchange and water loss in plants.

What are minute opening found in mature plant?
Stomata are minute openings in plants
