Diversity In Living Organisms
Why are blue green algae included under monera and not under plantae?
Blue green algae or cyanobacteria are prokaryotes and have nucleoid with naked DNA, i.e., nuclear material is not enclosed within a nuclear membrane. The cell organelles are also not enclosed with membrane. Blue green algae do not show multicellular body design like plants. All these characters show that the blue green algae belong to the kingdom monera rather than plantae.
