The cell membrane is a thin flexible layer around the cells of all living things. It is sometimes called the plasma membrane or cytoplasmic membrane. Its basic job is to separate the inside of cells from the outside. In all cells, the cell membrane separates the cytoplasm inside the cell from its surroundings.
Subsequently, one may also ask, is there a cell membrane in a animal cell?
All animals and plants are made of cells. Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells also have a cell wall, and often have chloroplasts and a permanent vacuole.
Why is the cell membrane so important to the survival of a cell?
The membrane is also pliable, which means it can move and flex in response to the surrounding environment. The fluid nature of the membrane is important because it allows the cell to survive in various environments. Your fingertips shrivel up because water is able to move through the cell membrane and exit the cell.
