What is parasite classification?

A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Protozoa.

Which phylum includes the parasitic animals?

Phylum Platyhelminthes
Phylum Platyhelminthes belongs to kingdom Animalia. This phylum includes 13,000 species. The organisms are also known as flatworms. These are acoelomates and they include many free-living and parasitic life forms.

Which is a characteristic of parasites?

In general, parasites share the following features: Parasites are usually smaller than their host. Parasites use both invertebrate and vertebrate hosts. Adult parasites may live on the host (e.g. lice), in the host (e.g. tapeworms) or feed on a host occasionally (e.g. mosquitoes).

Is nematode A parasite?

Nematodes are among the most abundant animals on Earth. They occur as parasites in animals and plants or as free-living forms in soil, fresh water, marine environments, and even such unusual places as vinegar, beer malts, and water-filled cracks deep within Earth’s crust.

Where is Platyhelminthes found?

Most freshwater flatworms are free-living and can be found in ponds, lakes, streams, ditches, and temporary puddles. They live under rocks, plants, and debris to avoid direct sunlight. They can be found on hard and soft substrates, but are more common on the hard surfaces.

What phylum does Plasmodium belong to?

Plasmodium is a unicellular eukaryote that belongs to the phylum Apicomplexa, formerly known as Sporozoa, probably the largest taxon of protists (Morrison, 2009). Almost all known apicomplexans (more than 5000 species have been described) are parasites of vertebrate or invertebrate hosts.

How are parasites classified in the human body?

Classes of parasites. Parasite are mainly classified into following two catagories; along with some other types of Parasites; Ecto-parasite (ectozoa): lives outside on the surface of the body of the host. Endo-parasite (entozoa): lives inside the body of the host: in the blood, tissues, body cavities, digestive tract and other organs.

Which is the branch of science that deals with parasites?

Parasitology is the branch of Science which mainly deals about all the Parasites and its infectious diseases. Whole Parasitology covers mainly Parasites, Host and its association between them.For having a very clear cut knowledge about Introduction and Classification of Parasites some important terms should be clear and those are:

What is the definition of a parasitic plant?

Parasitic plant, plant that obtains all or part of its nutrition from another plant (the host) without contributing to the benefit of the host and, in some cases, causing extreme damage to the host.

How are parasites and facultative parasites alike and different?

Species of parasitic plants also differ with regard to whether they need the host in order to complete their life cycle. Obligate parasites have an absolute requirement for a host, whereas facultative parasites can live and reproduce in the absence of a host. All holoparasites are, by definition, obligate.
