What is the cell that controls the size of a stoma?

It's actually the guard cells. Water vapor does go through it, though.


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 is the whole between two guard cells in a leaf called?

It's called a stoma (plural stomata) and its function is to allow carbon dioxide to enter the leaf for photosynthesis. The guard cells sre responsible for regulating the size of the stoma.

What are guard cells and what is their function?

Guard cells allows the exchange of oxygen and carbon dioxide in and out of the leaf. This is known as leaf exchange. When guard cells are full of water they swell up and close meaning no oxygen can leave or carbon dioxide can enter, but when the water is taken away from the cell they open up to allow oxygen to exit and carbon dioxide to enter.


What do stomata look like?

"Stoma" comes from Greek, meaning: mouth. It usually indicates openings, sometimes other than mouths. A stoma is a surgically created opening on the abdomen which allows stool or urine to exit the body. Stoma is also the name for small openings on the underside of leaves that facilitate transpiration.


What are the cells that control the openings on the underside of the leaf called?

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 opening that allow carbon dioxide and oxygen to move into and out of a leaf?

The answer is quite easy its the oxygen cells
