Animal cells never have cell walls. A plant cell does have a cell wall for support and protection. Animals have a cell membrane, which is composed of a phospholipid bilayer (made of polar, hydrophilic heads and nonpolar, hydrophobic tails) and do not have a cell wall. Animal cells never have cell walls.
Algae possess walls made of glycoproteins and polysaccharides such as carrageenan and agar that are absent from land plants. In bacteria, the cell wall is composed of peptidoglycan. The cell walls of archaea have various compositions, and may be formed of glycoprotein S-layers, pseudopeptidoglycan, or polysaccharides. Fungi possess cell walls made of the glucosamine polymer chitin. Unusually, diatoms have a cell wall composed of biogenic silica.
