Plants have pores on the underside of the leave called stomata (or stoma in singular). By opening or closing these pores, they allow the oxygen formed inside the plant to exit, and the carbon dioxide outside to enter.
Guard cells control the opening and closing of the leaves stomata.
the mono-dixon. its a rare cell only found in leafs:)
The Guard Cells of the Stomatal Aperture.
Cell phone GPS tracking works as long as you are on a road that is mapped. Going into a store won't change your location, but leaving the parking lot will.

Means to trade gases with another cell to make it develop of a form to make it larger
Cardiovascular
The cell membrane conrols all the substances that go in and out of the plant cell
The cell wall, which also protects the cell & controls the passage of objects from going inside and leaving the cell, also molds the shape of the cell.
yes, the cell membrane does keep material from entering or leaving the cell -karla cruz 7th grade

Diffusion
When a gas moves in and out of a cell it is called diffusion.
The structure is the cell membrane.
The process of substances leaving a cell is called diffusion. The cell membrane is a selective permeable membrane that only allows certain materials to enter or leave the cell.
Two primary gases are found in the blood stream. Leaving the capillaries and going out into the tissue is OXYGEN which was carried by the hemoglobin in the red blood cell. Leaving the tissue and entering the capillary is CARBON DIOXIDE or "CO2" which is transported via carbonated water (aka carbonic acid) in the plasma of the blood stream.
