The cell membrane is semi-permeable controlling the movement of substances in and out of the cell. It contains a phospholipid bilayer consisting of hydrophobic tails and hydrophilic heads. Also contained in the cell membrane are transport proteins.
The double layer fats in a cell are known as phospholipids, which make up the cell membrane. This lipid bilayer acts as a barrier that separates the internal environment of the cell from its external surroundings. The phospholipid bilayer also helps regulate the passage of substances in and out of the cell.
For most cells, it is the cell membrane. Cells have a plasma membrane that is very selectively permeable i.e, will allow entry of substances that are necessary for the cell functioning. In case of an egg cell, it is surrounded by follicular cells. It provides protection from various acidic conditions. For a plant cell, the cell wall serves as a barrier.
A cell membrane can be compared to a barrier or a gatekeeper. It regulates the movement of substances in and out of the cell, maintaining internal conditions necessary for the cell to function properly.
Hydrophobic molecules pass through cell membranes easily because the cell membrane is made up of a double layer of lipids, which are also hydrophobic. This allows hydrophobic molecules to dissolve in the lipid layer and pass through the membrane without resistance.
The outer layer of an animal cell is called the cell membrane. It controls what can go into and come out of the cell.

The cell membrane - the outer layer in animal cells and the layer beneath the cell wall in plants that is made up of a double layer of phospolipid molecules. The term semipermeable means that the outer layer only allows certain substances into and out of the cell, not everything.
The main functions of the cell membrane are to regulate the movement of substances in and out of the cell, provide structural support, and facilitate cell communication. The cell membrane is primarily made of phospholipids, cholesterol, and proteins.
