Cell wall - Wikipedia
https://en.wikipedia.org/wiki/Cell_wall
WebA cell wall is a structural layer that surrounds some cell types, found immediately outside the cell membrane. It can be tough, flexible, and sometimes rigid. Primarily, it provides the cell with structural support, shape, protection, and functions as a selective barrier.
