Detailed explanation-1: -The cell membrane is found in both animal and plant cell. It prevents the contents of the cell from spreading in all directions and protects the organelles from the external environment. It is selectively permeable and allows only selected molecules to move across a cell.
Detailed explanation-2: -Animal cells only have the cell membrane. The cell membrane is a semi-permeable covering surrounding the outside of the cell. Plant cell membranes are found on the outside of the cell cytoplasm and just inside the cell wall.
Detailed explanation-3: -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.
