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: -Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
Detailed explanation-3: -The cell membrane is present in all living organisms, including plants. It is the outermost layer of the cell in animals and encloses other cellular organelles within.
Detailed explanation-4: -Cell Membrane. The cell membrane is found in both plant and animal cells. It is a double-layer membrane made of lipids and proteins.
