What are the importance of plasma membrane?

Answer 1

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.

Answer 2

The plasma membrane is considered so important to the cell because it controls how substances con move in and out of the cell. It enables reactions to take place that would otherwise be impossible.

Answer 3

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.

Answer 4

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.

Answer 5

Plasma membrane in the primary membrane of a cell. Which protects the cell from being washed out or when attacked. Besides it also helps to make make contact with the neighbor cells. So,it is very important to a cell.

Answer 6

It tells the cell what can be allowed in and out to keep the cell healthy

Answer 7

plasma membrane surrounds the cell and protects it from bacteria and other parasites it is also important in the transportation of different materials across the cell
