The cell membrane exhibits selective permeability, allowing it to control which substances can enter and exit the cell. This characteristic is primarily due to its phospholipid bilayer structure, which is embedded with proteins that facilitate transport. Small, nonpolar molecules can easily pass through, while larger or charged substances require specific transport proteins or channels. This selective control is essential for maintaining homeostasis within the cell.
The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit the cell.

When a substance wants to enter a cell it goes through the cell membrane in a process called endocytosis.
