The correct option is B Algae - Methylase
Degrading of the cell wall gives rise to protoplasts as the cell walls are made up of a variety of polysaccharides. The cell walls can be degraded with a mixture of appropriate polysaccharide-degrading enzymes. Plant cell wall can be degraded with cellulose, pectinase and xylanase, Bacteria- lyssozyme and EDTA, Fungal cells-Chitinase. Algal cells can be degraded with chitinase, lysozyme, pectinase, sulfatase, β-glucuronidase, and laminarinase. Thus, the correct answer is option B.
