every living cell is surronded byu a living membrane called cell membrane which allows the passage of some molecules preventing the passage of others in this way maintains the internal composition to constant or nearly constant.
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
the cell membrane is as flexible barrier outside of the cell.

the cell membrane
The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.
The cell membrane consists of a lipid bilayer which is actually a phospholipid. Cell membranes are semipermiable and they regulate what enters and leaves the cell.

The carbohydrates help identify chemical signals and define the characteristics of the cell.
A eukaryote is an organism with cells with a nucleus and other organelles enclosed within a cell membrane.
smallest unit that displays the properties of life; always contains cytoplasm surrounded by a plasma membrane.
Cell membrane
Yes, the cell membrane is considered to be part of the protoplasm in a cell. Protoplasm includes all the living components of the cell, such as the cytoplasm and organelles. The cell membrane surrounds the cytoplasm and organelles, helping to define the boundary of the cell.
