Enlist the features of cell membrane.​

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

It is the outermost covering of a cell that separates the contents of the cell from its external environment.

It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.

Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.

Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.
