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.
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).
recognizes the common traits that eukaryotic organisms share,
such as nuclei, cytoskeletons, and internal membranes.
many books and articles still refer to them as "Archaebacteria",
that term has been abandoned because they aren't bacteria --
and colonial--including the true bacteria (eubacteria)
reproduction -- binary fission
cell nucleus nor any other membrane-bound organelles within
their cells, most but not all have a cell wall e.g., thermoplasma,
ARMAN (Archaeal Richmond Mine Acidophilic Nanoorganisms),
reproduce asexually by binary or multiple fission, fragmentation,
or budding; meiosis does not occur

a cell wall, organelles including a nucleus, but no chloroplasts.
They have no mechanisms for locomotion. Fungi range in size
from microscopic to very large ( such as mushrooms). Nutrients
are acquired by absorption, for the most part, from decaying
molds, mushrooms, yeasts, mildews, and smuts

own means of locomotion

ferns), gymnosperms, and flowering plants
reproduction involves the male pollen grains traveling to
the stigma of a flower
reproduction involves the production of a new plant without
the use of flowers.
