Feb 19, 2022 · The 5 kingdoms of life are Animalia, Plantae, Fungi, Protista, and Monera. When there are 6 kingdoms, Monera breaks into Eubacteria and Archaebacteria. In biology, a kingdom of life is a taxonomy rank that is below domain and above phylum.
He distinguished two kingdoms of living things: Regnum Animale ('animal kingdom') and Regnum Vegetabile ('vegetable kingdom', for plants). Linnaeus also included minerals in his classification system , placing them in a third kingdom, Regnum Lapideum .
Kingdom: Plantae, animalia, fungi, protoctista and prokaryotae. Phylum: Groups organisms according to body plan eg backbone. Class: Groups organisms to do with general trait eg number of legs....

- Archaebacteria. Archaebacteria are single-celled prokaryotes originally thought to be bacteria. They are in the Archaea domain and have a unique ribosomal RNA type.
- Eubacteria. These organisms are considered to be true bacteria and are classified under the Bacteria domain. Bacteria live in almost every type of environment and are often associated with disease.
- Protista. The protista kingdom includes a very diverse group of organisms. Some have characteristics of animals (protozoa), while others resemble plants (algae) or fungi (slime molds).
- Fungi. Fungi include both unicellular (yeast and molds) and multicellular (mushrooms) organisms. Unlike plants, fungi are not capable of photosynthesis. Fungi are important for the recycling of nutrients back into the environment.

Introduction. Plants are a large and varied group of organisms (Fig 1). There are close to 300,000 species of cataloged plants. Of these, about 260,000 are plants that produce seeds. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom.
There are close to 300,000 species of catalogued plants. 1 Of these, about 260,000 are plants that produce seeds. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. The plant kingdom contains mostly photosynthetic organisms; a few parasitic forms have lost the ability to photosynthesize.
