In the five kingdom classification, bacteria are included in Kingdom Monera.
Bacteria are cosmopolitan in distribution. These organisms show the most extensive
metabolic diversity. Bacteria may be autotrophic or heterotrophic in their mode of
nutrition. Kingdom Protista includes all single-celled eukaryotes such as
Chrysophytes, Dinoflagellates, Euglenoids, Slime-moulds and Protozoans. Protists
have defined nucleus and other membrane bound organelles. They reproduce
both asexually and sexually. Members of Kingdom Fungi show a great diversity
in structures and habitat. Most fungi are saprophytic in their mode of nutrition.
They show asexual and sexual reproduction. Phycomycetes, Ascomycetes,
Basidiomycetes and Deuteromycetes are the four classes under this kingdom.
The plantae includes all eukaryotic chlorophyll-containing organisms. Algae,
bryophytes, pteridophytes, gymnosperms and angiosperms are included in this
group. The life cycle of plants exhibit alternation of generations – gametophytic
and sporophytic generations. The heterotrophic eukaryotic, multicellular
organisms lacking a cell wall are included in the Kingdom Animalia. The mode of
nutrition of these organisms is holozoic. They reproduce mostly by the sexual
mode. Some acellular organisms like viruses and viroids as well as the lichens are
not included in the five kingdom system of classification.
