The cells that control the openings (stomata) on the underside of the leaf are called Guard Cells.
The guard cells are found on either side of each stoma. These guard cells can swell or shrink in size depending upon the environmental conditions.
(Stomata are structures through which gas exchange occurs and evaporation of water from the leaves take place.)
When the atmosphere has a high water content, the guard cells swell with water forcing the stoma to open and allows the exchange of gases. When the stoma is open, the plant also loses water through a process called transpiration (evaporation of water from the plant leaves).
In dry atmospheric conditions, the guard cells shrink in size to close the stoma preventing further loss of moisture from the plant.
What else can I help you with?
How does oxygen get out of the leaf cells and back into the air outside the plant?
Through a process called diffusion. This process is the random movement of molecules from an area of high concentration to an area of low concentration.
What sausage-shaped cells control the size of the openings that allow carbon dioxide and oxygen to move into and out of a leaf?
The guard cells of a stoma perform this function.
What sausage-shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of a leaf?
Guard cells control the size of openings (stomata) that allow carbon dioxide and oxygen to move into and out of a leaf. Guard cells change shape to open or close the stomata in response to environmental conditions like light intensity, humidity, and carbon dioxide levels.
What is the Tiny openings in the skin called?
The outer layer of the skin, the epidermis, consists mainly of cells called keratinocytes.
Are stoma located on the top of a leaf?
No, stomata are located on the underside of leaves. They are tiny openings surrounded by specialized cells that regulate gas exchange, allowing for the uptake of carbon dioxide and the release of oxygen during photosynthesis.
Where are guard cells found?
In pairs on the underside of leafs. They control the flow of gases into and out of the leaf. The two of them are called a stoma.
How does the structure of guard cells relate to the function of guard cells?
control the size of the openings called stoma the stoma allow gases such as carbon dioxide and oxygen to move into and out of the leaf
What sausage-shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of the leaf?
cardiac cells
How do carbon dixide get into the leaf?
it gets it by going through the guard cells and stoma
What cell control the size of openings that allow carbon dioxide and oxygen to move into and out of the leaf?
cardiac 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.
Where can stomata be found?
exchange of gases takes place by simple diffusion directly into each cell through the openings present in epidermis called stomata. Stomata are found on the underside of leaves. :)

The outer layer of the skin, the epidermis, consists mainly of cells called keratinocytes.
