As mentioned earlier, the cell wall is present in all plant cells, fungi, bacteria, algae, and some archaea. Amongst the first microscope images are those of cork, which – reportedly due to their visual appearance – led Robert Hooke to coin the term ‘cell’ (Hooke, 1665). Algae - Algae - Form and function of algae: Algal cells are eukaryotic and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion.

Knowledge on their chemical diversity is still limited and gaining further expertise on brown algal cell walls is crucial to precisely depict detailed structural variants. Algal cell walls contain either polysaccharides (such as cellulose (a glucan)) or a variety of glycoproteins (Volvocales) or both. There are different structures for cell walls depending on what we’re talking about. The molecules of the cellulose are chain-like and are formed by glucose residues held together by oxygen though beta-linkage.
