WebVirtually all prokaryotes, as well as the cells of plants, fungi, and some algae, have a cell wall—a rigid structure that surrounds the cell membrane. Most cell walls are composed of polysaccharides—long … Like plants, algae have cell walls. Algal cell walls contain either polysaccharides (such as cellulose (a glucan)) or a variety of glycoproteins (Volvocales) or both. The inclusion of additional polysaccharides in algal cells walls is used as a feature for algal taxonomy. • Mannans: They form microfibrils in the cell walls of a number of marine green …
