The cell membrane, also known as the ​

Placeholder

membrane, is found in ​

Placeholder

types of cells. It controls and ​

Placeholder

what is allowed in and out of the cell to help maintain ​

Placeholder

or a balanced environment. It also is known as the ​

Placeholder

because the different parts of the cell membrane can move around and are not fixed in one location.
