Technically, Linnaeus had a three-kingdom system which is preserved in the opening question in 20 Questions: "Animal, vegetable, or mineral?" The two kingdoms of life seemed pretty simple: animals moved and plants were planted. The microscope added microorganisms into the mix. Some one-celled organisms were plant-like; some were animal-like; but some were both or neither Bacteria did not have a nucleus.. Biochemistry revealed more. Fungi, although plant-like in growth, differ from plants in having chitin rather than cellulose in their cell walls and have mitochondria rather than chloroplasts.

Based on molecular biology, bacteria (monera) are split into two major groups (archaea, eubacteria), and the eukaryotes are split into six groups: animals, plants, fungi, are grouped with their closely related single-celled forms, and three other groups without multicellular forms are identified.

The 5 kingdom system of classification has been shown to be bullshit. The current system we use is the 3-domain one (Archaea, Eubacteria, Eukarya).

The 2-kingdom system was Aristotle's attempt at classification - included only Animals and Plants. The 5-k one called all unicellular non-eukaryotes "Monera", and devoted four entire kingdoms to eukaryotes, although the diversity was only superficial i.e. the genetic similarity, as it was found later, did not in any way reflect the morphological diversity.
