It controls what enters and leaves the cell, provides protection and separation for that cell, and provides a shape for the cell. It gives an anchoring point for the cytoskeleton and the cell wall (if appliccable) and can be involved in cell signalling pathways, which direct the cell to do things, or not to do things.

LaoThe plasma membrane is essential for maintaining cell structure and regulating the transport of substances into and out of the cell. It also plays a key role in cell signaling and communication with other cells. Additionally, the plasma membrane provides protection and support to the cell.
The plasma membrane, which serves as a diffusion barrier between the cell and its environment. All living cells have plasma membranes. A "diffusion barrier" prevents the loss of cellular materials by interfering with the physical tendency of molecules to spread out. It also prevents many substances from diffusing into the cell. And it also controls the movements of various substances and objects into and out of the cell.
The phospholipid bi-layer that constructs the plasma membrane of cells is made up of fatty acids that have a hydrophillic (water loving) head and a hydrophobic (water fearing) tail. Many phospholipids line up tail-to-tail to form a membrane. This layer is what holds cytoplasm within the cell. Without plasma membrane, life could not exist because cells would not exist. All living cells have a plasma membrane.

How does nutrients enter a cell?
The plasma membrane.
What is another name for the cell membrane that starts with P and is six letters long?
The cell membrane is also called the plasma membrane.
The cell membrane also is called the?
The cell membrane is also known as the plasma membrane or the cytoplasmic membrane. It is a biological membrane that separates all cells' interior from the outside, though can be permeated by selection ions and molecules. Its basic function is to protect the cell from its surroundings.
What is the structural model of the plasma membrane called-?
structural model of plasma membrane is called the selectively permeable membrane Structural model of the plasma membrane is called Fluid Mosaic Model.
Do plant and animal cells have a plasma membrane?
Yes, both plant and animal cells have a plasma membrane. The plasma membrane is a semi-permeable barrier that surrounds the cell and controls the movement of substances in and out of the cell.
