Apr 28, 2017 · Protozoa Definition. 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 ...
Protozoa (sg.: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris.
- Flagellates. Flagellates are a unicellular type of protozoans and are about 2,000 species. Some flagellates are free-living, such as Chlamydomonas. Some are parasitic, such as Trichomonas.
- Ciliates. Paramecium belongs to a group of protists that move about through numerous hairlike cilia, commonly referred to as ciliates. "Ciliophora" comes from the Latin term cilium, which means eyelid, and the Greek word phoros, which means bear.
- Sarcodina. Sarcodina, a type of protozoa, is a unicellular organism without definite shape. Its cell membrane is so flexible that it changes its shape constantly.
- Sporozoan. Sporozoans, a type of protist, are species of parasitic protists that produce spores at a certain stage of their life cycle. There about 2,000 known species of sporozoans.
Aug 3, 2023 · Some common examples of protozoa are Amoeba proteus, Paramecium caudatum, Euglena gracilis, Plasmodium falciparum, and Trypanosoma brucei. Classification of Protozoa. The modern classification of protozoa is based on the modified form proposed by Levine et al. in 1980.
6 days ago · protozoan, organism, usually single-celled and heterotrophic (using organic carbon as a source of energy), belonging to any of the major lineages of protists and, like most protists, typically microscopic. All protozoans are eukaryotes and therefore possess a “true,” or membrane-bound, nucleus.
Protozoa Classification and Examples. Protozoa is a phylum having unicellular heterotrophs. It comes under Kingdom Protista. Protozoa are divided into four major groups based on the structure and the part involved in the locomotion: 1. Mastigophora or Flagellated protozoans: They are parasites or free-living. They have flagella for locomotion
Classification. On the basis of light and electron microscopic morphology, the protozoa are currently classified into six phyla. Most species causing human disease are members of the phyla Sacromastigophora and Apicomplexa. Life Cycle Stages.
