What is the structure that surrounds a cell and controls what enters and leaves the cell?
The structure that controls traffic to and from the cell is the plasma membrane. It is not to be confused with the cell wall, which serves more to give structure to the cell.
Can you give me a sentence using the word cell membrane?
A plant cell has a cell membrane and a cell wall.
Why do plants have cell walls and animal cells don't?
Cell walls are used to give the cell strength and rigidity. This is important for plants, whereas animals have skeletons to do that job, and as such don't need the cell wall to do that.
Major functions of cell membrane proteins?
Examples of proteins in the cell membrane are pore/channel proteins, carriers, glycoproteins. Therefore protein assist in transport of substances across cell membrane. Cell recognition. Involved in mechanical strength and attachment of the cell membrane ( protein substances surround the cell membrane that allows it to attach to other cells)
What organelle regulates what goes in and out of the cell?
The cell membrane controls what enter and leaves the cell, it also gives the cell shape.
Why is cell wall present only in plants?
rpose of cell wall is to give rigidity to plants.
What cellular component would be responsible for the classic shape of a red blood cell?
'Spectrin' protein found in the outer cell membrane of the RBC Which give charctestics shape{BICONCAVE} .
Where is the cell membrane located and how is it different from a cell wall?
The cell membrane is located beneath the cell wall. The cell membrane is present in almost all types of cells whereas the cell wall is present in bacteria, fungi, algae, plant cell and is absent in protozoans and animal cells. The cell membrane is semipermeable and give support to the cytoskeleton of the cell, gives shape to the cell and helps in the formation of tissues whereas the function of the cell wall is to provide strength and rigidity to the cell, protects the cell against mechanical forces. The cell membrane is not elastic but permeable whereas the cell wall is elastic and controls turgidity. The cell membrane is found in animal cells wheres the cell wall is found in plant cells. The cell membrane is made up of lipids and proteins whereas the cell wall is made up of cellulose.
What structures do bacteria have and what are their functions?
Cell wall provides shape and give rigidity to the cell and provides a barrier to the enviroment
What is the structure that surrounds a cell and controls what enters and leaves the cell?
The structure that controls traffic to and from the cell is the plasma membrane. It is not to be confused with the cell wall, which serves more to give structure to the cell.
Does the membrane give instructions to the cell?
no the nucleus does
Can you give me a sentence using the word cell membrane?
A plant cell has a cell membrane and a cell wall.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
Can you give examples of a sentence with the word membrane in it?
A cell membrane is a substance that surrounds a cell. hope this helped! :P
The bilayer arrangement of molecules in a cell membrane give the cell a?
barrier
How does the cell membrane's function give the cell membrane its function?
The cell membrane regulates the entrance and exit of substances thus maintaining internal balance. It also protects the inner cell from damage and helps a cell.
What type of cell membrane do cells have?
The cell's membrane is "selectively permeable" because the cell allows some materials to enter or leave.I'm in grade eight. This is what my Science textbook says:"Because the cell membrane allows certain substances to enter or leave, but not others, it is said to be selectively permeable."
