Six Kingdoms of Living Things: Notes

Kingdom is the highest rank used in the biological taxonomy of all organisms. There are 6 kingdoms in taxonomy. Every living thing comes under one of these 6 kingdoms. The six kingdoms are Eubacteria, Archae, Protista, Fungi, Plantae, and Animalia.

History

Until the 20th century, most biologists considered all living things to be classifiable as either a plant or an animal. But in the 1950s and 1960s, most biologists came to the realization that this system failed to accommodate the fungi, protists, and bacteria.

By the 1970s, a system of Five Kingdoms had come to be accepted as the model by which all living things could be classified.

At a more fundamental level, a distinction was made between the prokaryotic bacteria and the four eukaryotic kingdoms (plants, animals, fungi, & protists).

The distinction recognizes the common traits that eukaryotic organisms share, such as nuclei, cytoskeletons, and internal membranes.

Although many books and articles still refer to them as "Archaebacteria", that term has been abandoned because they aren't bacteria -- they're Archaea.

Prokaryotes (simple cells no nucleus) / Methanogens: Create methane
Halophiles: High Salt
Thermophiles: Heat
Eubacteria / Live Everywhere, EXCEPT extreme environments, including on you.
Harmful and beneficial / Autotrophs
Some photosynthetic:
Some absorb food
