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 sausage-shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of a leaf?
cardiac cells
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 is the Tiny openings in the skin called?
The outer layer of the skin, the epidermis, consists mainly of cells called keratinocytes.
How do guard cells regulate the exchange of gases between a leaf and the air?
The guard cells regulate the exchange of gases between the leaf and air through the use of openings called stomatal pores.
Where do plants get co2 from in order to carry out photosynthesis?
From the atmosphere surrounding the plant. Carbon dioxide diffuses in through the stomata of the leaves, which are openings controlled by cells called guard cells.
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.
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. :)
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

cardiac cells
How do roots of plants get oxygen needed by them for breathing?
Plants respire through tiny openings or holes called stomata that are present on the underside of the leaves. Stomata trap air (like oxygen) and the exchange of gases takes place in side the plant cells.
What cell control the size of openings that allow carbon dioxide and oxygen to move into and out of the leaf?
cardiac cells
Where does water vapor exit and CO2 enter a leaf?
There are openings on the underside of a leaf called stomates. They have guard cells shaped like lips. They open and close to allow CO2 in and H2O and O2 out. It works using hydrostatic pressure.
What sausage shaped cells control the size of openings that allow carbon dioxide and oxygen to move into and out of of a leaf?
The guard cells of a stoma perform this function.
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.
Which process illustrates a feedback mechanism in plants?
A process that illustrates a feedback mechanism in plants is when the guard cells change the size of a leaf's openings to control gas exchange. Guard cells are located in the epidermis of leaves.
What is the Tiny openings in the skin called?
The outer layer of the skin, the epidermis, consists mainly of cells called keratinocytes.
