The cell membrane, also known as the plasma membrane, is a semi-permeable barrier that surrounds the cell. It is composed of a phospholipid bilayer with embedded proteins. The main characteristics of the cell membrane include controlling the movement of substances in and out of the cell, maintaining cell shape and integrity, and facilitating cell communication and signal transduction.
What is a characteristic of cell membranes?Answer this question…
selective permeability
Animal cells have a cell membrane; plant cells have both a cell membrane and a cell wall. Thus bacteria are plants.
The cell membrane acts as a barrier, controlling the entry and exit of substances into and out of the cell. It is composed of a phospholipid bilayer with embedded proteins that help in cell recognition, cell signaling, and transport of molecules. The cell membrane is selectively permeable, allowing only specific substances to pass through.
The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit the cell.

The fluid mosaic model describes the cell membrane as a fluid structure where lipids and proteins are able to move around and change position. This constant shifting allows the cell membrane to maintain flexibility and adapt to changing conditions.
selective permeability
Selective permeability is the characteristic of the cell membrane that allows only certain molecules and ions to enter or exit the cell. This feature helps regulate the internal environment of the cell by controlling what substances can pass through.
