unicellular irregular eukaryote

Answer 2

Answer:

Explanation:

The term protozoa implies 'first animals'. As the primary hunters of the microbial world, protozoa help in continuing the equilibrium of bacterial, algal and other microbial life forms.

Protozoa also means 'little animal'. They are named so because many species act like small animals. They search for and collect other microbes as food. Previously, protozoa were specified as unicellular protists possessing animal-like characteristics such as the capability to move in water. Protists are a class of eukaryotic microorganisms which are a part of the kingdom Protista.

The term 'protozoan' has become debatable. Modern science has shown that protozoans refer to a very complex group of organisms that do not form a clade or monophylum. This has led scientists to give up the term protozoa. Hence, the sub-kingdom Protozoa is not used today. Currently, protozoa are defined as single-celled, heterotrophic, or colonial eukaryotes possessing non-filamentous structures

                                  Characteristics of Protozoa

1. Protozoa do not have a cell wall and therefore can have a variety of shapes. Nevertheless, some of the protozoans have a pliant layer, a pellicle, or a stiff shell outside the cell membrane.
2. Protozoa vary in size and shape. Their sizes range from 10 to 55 micrometers, but they can be as large as 1 mm. The largest protozoa are called xenophyophores, which can measure up to 20 centimeters in diameter.
3. Protozoa prefer living in moist and aquatic habitats. Their cysts can be found in the bleakest parts of the ecosphere.
