A cell wall is a structural layer that surrounds most types of cells, situated outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Cell walls are absent from Mycoplasma bacteria, animal, and human cells.
