1. Eubacteria
"Bacteria are ubiquitous, mostly free-living organisms often consisting of one biological cell... Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbor membrane-bound organelles." (Wikipedia: Bacteria, 8.11.21 UTC 02:25)
2. Archaebacteria
"Archaea constitute a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes... Archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably for the enzymes involved in transcription and translation." (Wikipedia: Archaea, 8.9.21 UTC 11:09)
3. Protozoa
"Protozoa is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris." (Wikipedia: Protozoa, 8.16.21 UTC 14:43)
4. Chromista
"Chromista is a biological kingdom consisting of single-celled and multicellular eukaryotic species that share similar features in their photosynthetic organelles (plastids). It includes all protists whose plastids contain chlorophyll..." (Wikipedia: Chromista, 6.9.21 UTC 00:42)
5. Plantae
"Plants are mainly multicellular organism, predominantly photosynthetic eukaryotes... By one definition, plants form the clade Viridiplantae, a group that includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, mosses and the green algae, but excludes the red and brown algae." (Wikipedia: Plants, 8.4.21 UTC 15:50)
6. Fungi
"A characteristic that places fungi in a different kingdom from plants, bacteria and some protists is chitin in their cell walls. Fungi, like animals are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize." (Wikipedia: Fungus, 8.14.21 UTC 18:42)
7. Animalia
"Animals are multicellular, eukaryotic organisms... With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development." (Wikipedia: Animal, 8.11.21 UTC 18:04)
