That's like asking why do we need skin or why do milk need cups or why bear needs skin. The cell membrane protects what is inside the cell and keeps it stable. Also, the cell membranes are selectively permeable and only not allows everything to let in the cell, but going back to the first reason, if cells did not have membranes, we would look like a slime.

∙ 15y agoA cell needs a cell membrane to contain all of the organelles, and to control the flow of molecules and other objects from coming into the cell and out of the cell. The cell membrane controls whether an object can come into the cell or not. A cell membrane is selectively permeable meaning that it decides what to let into the cell and what to let out. this means harmful substances will be kept out while nutrition or such can get in, at the same time his allows excretion to happen.

Reproduction would not occur if which part of a cell was removed?
The Cell Membrane
What purpose would a cell use a lipid monomer?
The purpose a cell would have to use a lipid monomer would be for use for the cell membrane. The cell membrane protects the contents of the cell.
Do any of the Cells lack a Cell membrane?
Yes, all cells have a cell membrane. A cell membrane is necessary because it controls what materials go in and out of a cell. Without it, many harmful products would go into a cell and the cell would be destroyed.
Which cell structure controls the movement of materials into and out of the cell?
M for membrane I would suppose.
Is a thick outer covering outside the cell membrane?
Well, it depends on what type of cell you are talking about. If it's an animal cell, the outer covering would be the cell membrane. In a plant cell, the outermost one is the cell wall, then the cell membrane.
Does plant cells need a cell membrane?
Yes plant cells need a cell membrane. In addition to the cell membrane they also have a cell wall. Animal cells however do not have a cell wall but merely a membrane. A cell is not able to live without a membrane as it holds the organelles and cytoplasm in place.
What does the cell membrane need to survive?
It will need more cell membrane to cover it but cells only grow a certain size before they will no longer be efficient.
What would best represent a cell membrane in the sport of softball?
what would best represent a cell membrane in an animalcell what would best represent a cell membrane in an animalcell

The Cell Membrane
Why do you need cholesterol in the cell membrane?
It prevents the lipids on the cell membrane from sticking together
What part of a factory would be the Nuclear membrane?
in a plant cell the cell membrane would be the plaster on the walls. in an animal cell the cell membrane would be the walls, doors and windows.
What would a cell membrane be if the cell was a car?
The fenders, roof, hood and truck lid would be like a cell membrane.
Which organelle is found in both plant and animal cells and only allow certain things to pass in and out of the cell?
The cell membrane who ever is looking this up the cell membrane is what let things go in and out of the cell it is also known as the traffic cop:) if need any more answers look up the answer by typing in the search bar up above Thank you :)
What would be the cell membrane of a computer?
The casing to the computer or the covering for the computer would be similar to a cell membrane.
What would be appropriate for making the cell membrane in a cell model?
A good item for a cell membrane would be a thin plastic or cardboard
Why does the cell need a cell membrane?
because they need to keep them self save
What purpose would a cell use a lipid monomer?
The purpose a cell would have to use a lipid monomer would be for use for the cell membrane. The cell membrane protects the contents of the cell.
