2017年4月27日 · A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls.
Cell wall - Wikipedia
A 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. [1]
Cell Wall: Definition, Structure, & Functions with Diagram
2020年7月16日 · The cell wall is a rigid and protective outer covering commonly found in both prokaryotic and eukaryotic organisms such as plants, fungi, algae, bacteria, and archaea, but is absent in all animal cells. It is a non-living structure that varies in color and composition depending on the type of organism, and is freely permeable to natural substances.
