Algae and Fungi are differentiated on the basis of their mode of nourishment, Algae is Autotrophic while fungi are heterotrophic in the mode of nourishment. The relation of plant classification to other sciences such as biochemistry, ecology, and phytogeography is considered, and connexions between taxonomy and phylogeny are reviewed. Every classification was based on phylogeny and thus the plants were arranged in an ascending series from the most primitive to the most complex one. The five-kingdom proposed consist of: Kingdom Prokaryotes (Monera, or bacteria) These are prokaryotic unicellular organisms.
