what are the major characteristics of protozoa?

['They do not have cell wall; some however, possess a flexible layer, a pellicle, or a rigid shell of inorganic materials outside the cell membrane.', 'They have the ability during their entire life cycle or part of it to move by locomotor organelles or by a gliding mechanism.']

Prokaryotes are unicellular organisms that lack membrane-bound structures, the most noteworthy of which is the nucleus. Prokaryotic cells tend to be small, simple cells, measuring around 0.1-5 μm in diameter. While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions.

['The Monerans are unicellular organisms.', 'They contain 70S ribosomes.', 'The DNA is naked and is not bound by a nuclear membrane.', 'It lacks organelles like mitochondria, lysosomes, plastids, Golgi bodies, endoplasmic reticulum, centrosome, etc.', 'They reproduce asexually by binary fission or budding.']

['They do not have a backbone.', 'They are multicellular. ... ', 'They have no cell walls, like all other animals.', 'They reproduce by two reproductive cells, or gametes, coming together to produce a new organism of their species.']

As a protozoan and a member of the kingdom Protista that has animal-like qualities, an amoeba has to find and eat its food (since it is unable to make its own food as plantlike Protists do). Of the many species of amoeba, some live in water and soil, while others are parasites and live inside plants or animals.

Characteristics of Protists A eukaroytic organism can be unicellular or multicellular; most (but not all) protists are actually unicellular. Unlike bacteria, protists have specialized organelles, including a true nucleus confined by a nuclear membrane. This compartmentalization differentiates protists from bacteria.

Paramecia are eukaryotes. In contrast to prokaryotic organisms, such as bacteria and archaea, eukaryotes have well-organized cells. The defining features of eukaryotic cells are the presence of specialized membrane-bound cellular machinery called organelles and the nucleus, which is a compartment that holds DNA.

Characteristics of Archaebacteria Archaebacteria are obligate anaerobes, i.e., they flourish in the strict absence of oxygen and that is why only they can undergo methanogenesis. The cell membranes of the Archaebacteria are composed of lipids. The rigid cell wall provides shape and support to the Archaebacteria.

['Their body is dorsoventrally flattened.', 'They exhibit bilateral symmetry.', 'Also, they are triploblastic, with three germ layers.', 'They do not have a body cavity and are acoelomate.', 'The body is soft and unsegmented.', 'They are mostly parasitic with a few free-living.']

['They are widely distributed, aquatic or terrestrial, parasitic or free-living.', 'Their body is elongated, cylindrical, unsegmented, worm-like, bilaterally symmetrical and tapering at both ends.', 'They are triploblastic animals with perivisceral cavity more extensive than that of platyhelminths.']

['They have asexual reproduction, so an organism can produce its descendants.', 'They can be eukaryotes or prokaryotes.', 'Their internal part is formed by a liquid different from their external environment that allows the realization of biological processes.']

Kingdom fungi contain molds and yeasts. The key difference between fungi and protozoa is that the fungi are mainly multicellular eukaryotic organisms while protozoa are unicellular eukaryotic organisms.
