The membrane allows the cell to keep all its resources and materials together. Otherwise everything would drift away.
The cell membrane is permeable to some materials, allowing them to pass through into the cell without energy expenditure.
Similarly the membrane is impermeable to some materials. This allows the cell to do things like create a charge or concentration gradient by using active transport of the material. This is how cells maintain their Na and K concentrations which is very important to cell function.
What else can I help you with?
What is the advantage of the presence of on cell membranes?
the membrane has a greater surface area for an increased rate of diffusion
Do cheetahs have cell walls or membranes?
Cheetahs do not have cell walls. However, like all living organisms, they have cell membranes that surround and protect their cells. Cell membranes regulate the passage of substances in and out of the cell.
Do protist have cell membranes?
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
What do cell membranes do for the body?
Cell membranes act as a barrier, controlling the movement of substances in and out of the cell. They help maintain cell shape and provide support. Additionally, cell membranes are important for cell communication and recognition.
What functions do cell membranes do?
cell membranes monitor what goes into and out of a cell. only animal cells have a cell membrane. hope this is ok

Does calcium depolarize or hyperpolarize cell membranes?
Calcium depolarizes cell membranes.
Do plants have cell membrane?
Plants have cell membranes just inside their cell walls. The cell membranes control what passes into and out of the cell.
Are cell membranes hard?
Cell membranes are not hard at all they are actually quite softish....
What cell has cell membranes?
plant

Do fungi have cell membranes?
Yes. Like plants they have both cell membranes and cell walls (but the cell walls have a different composition).
Are cell membranes considered to be semipermeable membranes?
Yes.
Do all cells have cell membranes?
Yes, the cells of archaebacteria, bacteria, protists, fungi, plants and animals all have cell membranes. (Viruses have protein coats, not cell membranes and thus are not true 'cells'.) Thus indeed, all cells possess a cell membrane.
