it controls what enters and exits the cell
----------------------------------------------------------------
It holds the cell contents together and forms a barrier between these contents and what is outside the cell. It also has structures in it that allow for the controlled transport of specific substance into and out of the cell.

Also, the outer layer is occupied by glycoproteins that have attached sugars, and these act as a kind of fingerprint of the cell, allowing it to be recognised by other cells and important compounds like hormones. It lets some molecules in and keeps some out For example, the cell membranes of the villi in the small intestine let nutrient molecules into the bloodstream, but leave the large ones out.

What role do membranes play in prokaryotes?
Prokaryotic cells do not have membrane bound organelles. The membrane controls the movement in and out of the cell.
What role do the cell wall and cell membrane play in a cell?
It is important to remember the following: Animal cell: Cell membrane, Plant cell: Cell membrane, cell wall. The role of a cell membrane is to monitor what exits and enters the cell and therefore maintain the internal environment of it, to contain the contents of the cell and to provide some sort of protection for it. The role of a cell wall which is unique only to plant cells, is to protect the cell inside and lend support to it so it can maintain its stucture.
What are organelles that play a major role in the cell division?
The cell membrane. But if the cell is a plant cell, the cell membrane and cell wall work together to accomplish this task.
How do the endoplasmic reticulum and cell membrane work together?
The ER, does not only play a major role in creating protiens, but also helps transport proitiens to the cell membrane. Here they can then leave the cell if needed.
The main role for the cell membrane is to?
regulate the movement of substances in and out of the cell. It acts as a barrier, controlling the exchange of nutrients, waste products, and other molecules between the cell and its environment. Additionally, the cell membrane is involved in cell signaling and communication.
What role of the cell membrane and cell wall play in the cell?
Separate the living organism from the nonliving environment around it.
What role do membranes play in prokaryotes?
Prokaryotic cells do not have membrane bound organelles. The membrane controls the movement in and out of the cell.
What role do the cell membrane play in the cell?
they work as a barrier: ions can't pass through. They also have a metabolic role: signaling, or communication (cell to cell interaction)
What role do cell membrane play in prokaryotic cell In eukaryotic cell?
In Prokaryotic cells, membrane controls what enters and leaves the cell, they also give the cell a shape and keep organells together.

What is the role of the cell membrane in cell membrane?
Acts as a protective layer and allows materials to enter or leave.
What cell part plays a role in diffusion?
The plasma membrane of a cell plays a role in diffusion.
What is the role of micro filaments in cell division?
they pull the cell membrane in
