The cell membrane.
The cell's membrane allows only certain substances to diffuse in and out of the cell.
The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.
The permeability of the cell membrane controls which substances may pass in or out of the cell.

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.

the cell wall
The process of substances leaving a cell is called diffusion. The cell membrane is a selective permeable membrane that only allows certain materials to enter or leave the cell.
The cell membrane, composed of phospholipids and proteins, allows for selective permeability. Its structure enables it to regulate the passage of molecules in and out of the cell, ensuring that only certain substances can cross based on their size, charge, and solubility.
As the cell membrane only allows certain substances to enter or leave the cell, meaning that while it IS permeable (as some substances can cross it), it is only selectively as not all substances are able to cross it, only some.
