The cell membrane, also called the plasma membrane, is a thin layer that surrounds the cytoplasm of all prokaryotic and eukaryotic cells, including plant and animal cells. It is a selectively permeable cell organelle,allowing certain substances inside the cell while preventing others to pass through and thus is analogous to a barrier or gatekeeper in their function.

A mitochondrion (/ ˌ m aɪ t ə ˈ k ɒ n d r ɪ ə n /, plural mitochondria) is a double membrane-bound organelle found in most eukaryotic organisms. Mitochondria generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy.

brane, an argument that went to the very heart of the subject of membrane structure and function. As we will see shortly, cell membranes contain a lipid bilayer, 

Some of them may act as antigens, receptor molecules (e.g., insulin binding sites of liver plasma membrane), regulatory molecules and so on. Cell membrane is made by two layers of lipid films (oil molecules) with many kinds of membrane proteins. Cell membrane controls the movement of molecules such as water, ions, nutrients, and oxygen in and out of the cell. Proteins on the cell membrane also involved in cell movement and the communication between cells.
