Question

Which part of the cell controls what enters and leaves the cell?​

Answer 1

The part of the cell that controls what enters and leaves the cell is "Cell membrane"

Explanation:

• Cell membrane is also called as Plasma membrane.

• It separates interior components of the cell from its outer space.

• It provides structure to the cell.

• It is the entry and exit point of a cell.

• It also protect the cell from the attack of virus, bacteria and pathogens.

• Cell membrane allows only specific substances and molecules to enter or exit a cell. Therefore, it act as a 'selective barrier'.

Answer 2

The plasma membrane, commonly known as the cell membrane, separates the interior of the cell from the outside. The thin membrane that covers every living cell is known as the cell membrane. A cell is surrounded by a double layer of lipids and proteins.

The fundamental role of the cell membrane is to regulate the entry and exit of substances into and out of the cell, as well as to maintain the cell's internal environment.

The cell membrane of animal cells regulates what goes in and out of the cell. Ionic channels, ion pumps, symport, ion-exchange systems, antiports, receptors, and other plasma membrane-bound components regulate the influx and outflow of various substances across the cell membrane.
