Question

define protozoa? tell the features

Answer 1

CHARACTERISTICS OF PROTOZOA:Protozoa are generally microscopic animals whose bodies are not divided into cells, they are therefore called non-cellular or unicellular animals. ... Their single-celled bodies are complete organism which perform all the activities of higher multicellular forms.

Answer 2

Protozoa (also protozoan, plural protozoans) is an informal term for single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris.[1][2] Historically, the protozoa were regarded as "one-celled animals", because they often possess animal-like behaviors, such as motility and predation, and lack a cell wall, as found in plants and many algae.[3][4]Although the traditional practice of grouping of protozoa with animals is no longer considered valid, the term continues to be used in a loose way to identify single-celled organisms that can move independently and feed by heterotrophy.
