Apr 27, 2017 · 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.
The composition of cell walls varies across taxonomic groups, species, cell type, and the cell cycle. In land plants, the primary cell wall comprises polysaccharides like cellulose, hemicelluloses, and pectin. Often, other polymers such as lignin, suberin or cutin are anchored to or embedded in plant cell walls.
Jul 16, 2020 · 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.
Mar 15, 2019 · A cell wall provides an additional layer of protection on top of the cell membrane. It is found in plants, algae, fungi, prokaryotes and eukaryotes. The cell wall makes plants rigid and less flexible. It is primarily made up of carbohydrates like pectin, cellulose and hemicellulose.
