What are Protozoa and their types
Answers
Answer:
Organisms known as protozoa include a wide range of organisms, most of which are free-living single-celled eukaryotes. Therefore, protozoa fit into the Domain Eukarya. Although the different phyla of the kingdom Protista are not closely related, they are nonetheless classified together because of their large differences from the other kingdoms of plants, animals and fungi. The name “protozoa” has a dynamic history, at one time including only the “animal-like” unicellular forms of life. Today, these heterotrophic protozoa are lumped together with the autotrophic algae and other simple forms of life into the Kingdom Protista. While all protozoa are eukaryotes, not all reproduce with the standard model of mitosis that is seen in higher animal cells. Many have complex cellular division that resembles binary fission in bacteria, on a larger scale. Some phyla in the Kingdom Protista are autotrophic cells, containing chloroplasts which can produce sugars from sunlight. Although only heterotrophic organisms were considered protozoa historically, this article will present many of the phyla within Protista that can photosynthesize sugars. Below is an image of a ciliate protozoa.
Answer:
Organisms known as protozoa include a wide range of organisms, most of which are free-living single-celled eukaryotes. Therefore, protozoa fit into the Domain Eukarya.
These are divided into four major groups.
(1) Amoeboid protozoans or sarcodines.
(2) Flagellated protozoans or zooflagellates.
(3) Ciliated protozoans or ciliates.
(4) Sporozoans.
