Cell Membrane

Summarized by Plex Health
Last Updated: 01 May 2022

The plasma membrane, called the cell membrane, is the membrane found in all cells that divides the interior of the cell from the outside environment. In microbial and plant cells, a cell wall is affixed to the plasma membrane on its outside surface. One is to transport nutrients into the cell and additionally to deliver poisonous substances out of the cell. Another is that the membrane of the cell, which would be the plasma membrane, will have proteins on it which communicate with other cells. And those proteins which stick beyond the plasma membrane will enable one cell to engage with another cell. The cell membrane additionally provides some structural support for a cell. And there are various types of plasma membrane layers in different types of cells, and the plasma membrane has in it generally a lot of cholesterol as its lipid element. In truth, they have a cell wall beyond them, and that cell wall is much harder and is structurally more sound than a plasma membrane is.
