guard cells
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.

Stomata
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.
There are a large number of tiny pores called stomata on the surface of leaves of plants (The singular of stomata is stoma).Each stomatal pore (or stoma) is surrounded by a pair of guard cells .The opening & closing of stomatal pores are controlled by the guard cells.

Guard Cells surround the stomata, and enable it to open or shut.

Stomata
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.
Paracytic stomata are a type of stomata found in the leaves of plants. They have two subsidiary cells that are parallel to each other and perpendicular to the opening of the stomata pore. This arrangement helps regulate the opening and closing of the stomata to control the exchange of gases and water vapor with the environment.
The opening is called a stomata, which is regulated by two guard cells.
Stomata are found in the epidermis of leaves, specifically in specialized cells called guard cells. Guard cells surround and control the opening and closing of the stomata to regulate gas exchange and water loss in plants.

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.
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.
Stomata and guard cells are called turgor-operated valves because their opening and closing are regulated by changes in turgor pressure within the guard cells. When the guard cells become turgid from water uptake, they bow outwards and cause the stomatal pore to open. Conversely, when the guard cells lose water and become flaccid, the pore closes.
