Question

Do all organism have a cell membrane?

Answer 1

Yes, all organisms have a cell membrane. It is one of the basic component of cell that encloses the other basic components-cytoplasm and nucleus. The cell membrane separates the cells from one another and controls the movement of materials in and out of the cell. Both plant and animals have cell membrane. In plants it is inside the cell wall and in animals it is the outer layer of the cell.
