What controls the entering and leaving of a cell?
cell (plasma) membrane
What cell part provides support for the cell allows gases and water to pass through and provides protection?
The cell wall is the structure that provides support for the cell, allows gases and water to pass through, and provides protection by maintaining the cell's shape and rigidity. It is found in plant cells, bacteria, fungi, and some protists.
What controls the materials going in and out of a cell?
The Cell Membrane Makes Sure that the materials going in and out of the cell are not harmful, such as a virus.
What might happen if the amount of water entering and leaving the cell were not controlled will the cell swell or shrink?
The cell membrane and all its organelles would burst.
Why is surface area an important factor in limiting factor in limiting cell growth?
The materials entering or leaving a cell need to pass through the cell surface.
What do the parts of an animal cell do?
The cell membrane conrols all the substances that go in and out of the plant cell
Why does a plant have a rectangle shape 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.
Does the cell membrane keep materials from entering or leaving the cell?
yes, the cell membrane does keep material from entering or leaving the cell -karla cruz 7th grade
What controls the entering and leaving of a cell?
cell (plasma) membrane
What is The process of substances leaving a cell called?
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.
How does dissolved gases pass in and out of a cell?
Diffusion
What is the movement of gases in and out of a cell called?
When a gas moves in and out of a cell it is called diffusion.
What gas moves from the heart muscles to the capillaries?
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.
What is the purpose of the guard cell in a plant?
for exchange of gases
What do Golgi bodies do for a cell?
they usually package large particles leaving the cell through exocytosis.
If a cell is dropped into a solution and the cell shrinks what should be assumed about the solution?
The solution is likely hypertonic and water is leaving the cell.
What gases are exchanged across a cell membrane and how?
nitrogen and hydrogen
