Protozoa, from the Greek meaning âfirst animalâ, refers to simple, eukaryotic organisms composed of a microscopic single cell. Reproduction is through simple asexual cell division, or binary fission, in which two daughter cells are formed or, if many daughter cells are formed, multiple fission.moebae: These are the simplest of the protozoa and are characterised by a feeding and dividing trophozoite stage that moves by temporary extensions of the cell called pseudopodia (âfalse feetâ). In some species the trophozoite can form a resistant cyst stage able to survive in the environment.
Protozoa usually does not have cell walls, but some phyla may be surrounded by a shell. Protozoa has alternative generation between vegetative form (trophozoite) and the resting spore called cyst. Most protozoa cells are multinucleate, but some have single nucleus. They have contractile vacuoles, which remove excess water. They have a special kind of motion using three types of locomotors such as flagella, cilia, and pseudopodia. Flagella and cilia have a similar structure to (9+2) system of microtubules.
