Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Every cell is surrounded by a thin membrane. What is the main function of this cell membrane?
A
to separate the inside of the cell from the outside environment
B
to allow each cell to form connections with other cells
C
to limit the size of the cell and keep the shape of the cell the same
D
to protect the cell from invasion by bacteria and viruses
Explanation: 

Detailed explanation-1: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-2: -The cell membrane is also called the plasma membrane. It provides protection for the cell and its cellular components from the external environment. It is selectively permeable and regulates the movement of molecules in and out of the cell.

Detailed explanation-3: -The four main functions of the plasma membrane include identification, communication, regulation of solute exchange through the membrane, and isolation of the cytoplasm from the external environment.

Detailed explanation-4: -The plasma membrane Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
