Therefore, they appear leaf-like or ribbon-like creatures. They include Fasciola hepatica (liver fluke), Taenia solium (tapeworm), Schistosoma (blood fluke), Planaria etc. General features of Platyhelminthes: They are mostly parasitic (e.g. tapeworm, liver flukes). However, some may be free living (e.g. Planaria). True body cavity is absent.
Example: Taenia. Class Trematoda. The trematodes, or flukes, are parasites of mollusks and a variety of different organisms, such as humans. They also have suckers as they are parasites and obtain food by sucking substances from the host. Example: Liver fluke. Examples of Phylum Platyhelminthes. Dugesia (Planaria): A free-living flatworm with

Ascaris. The flatworms are the largest group of acoelomate worms. Although the flatworm body plan is relatively simple, it is a great deal more complex than that of a. May 16, 2012 The majority of members of the phylum Platyhelminthes (the flatworms—a phylum that includes the notorious tapeworms and flukes) are parasitic; Is incomplete (mouth, intestine, no anus) in both "planarians" and "flukes". These flatworms Is totally absent (no mouth no intestine, no anus) in "tapeworms". These flatworms Examples: **"Human/ Student will compare flatworm body plan with roundworm and earthworm Remind students that both the tapeworm and the liver fluke are parasitic organisms.

Tape worm Tapeworm Infestation is the infection of the digestive tract by adult parasitic flatworms 2017-12-06 · The tapeworm infection is also a common infection of the gastrointestinal system. Many different tapeworm species are involved in the onset of the infection which includes Taenia saginata, Taenia solium, and Diphyllobothrium latum. They are mostly present in partially cooked or undercooked meat and fish. These tapeworms live by absorbing nutrients from the intestines of its host.

Slide A - Planaria (w.m.) - External view Slide B - Planaria Digestive Tract (w.m.) - Internal view Slide C - Fasciola hepatica (sheep liver fluke) Slide D - Clonorchis sinensis (human liver fluke) Slide E - Taenia pisiformis (dog tape worm) - Internal view (large, proglottid - show eggs & gental pore, etc. also). (c) The Trematoda class includes Fascioloides magna (right) and Fasciaola hepatica (two specimens of left, also known as the common liver fluke). (d) Class Cestoda includes tapeworms such as this Taenia saginata. T. saginata, which infects both cattle and humans, can reach 4–10 meters in length; the specimen shown here is about 4 meters.

Ingest in larval stage from fish, fluke as cysts enter duodenum. Cysts reach intestine and hatch; flukes then move to the liver (biliary ducts). Adults mate and lay eggs. eggs pass out in feces. Eggs are then ingested by a snail. Several larval stages occur in snail; the latest stage called Cercaria burrows out of the snail.

They are acoelomates and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. Planaria, liver fluke, and Taenia all are flat worms. So, the correct answer is option A. Answer verified by Toppr
Tape worm (Taenia solium) Parasitic adaption.
Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum Platyhelminthes.It infects the livers of various mammals, including humans, and is transmitted by sheep and cattle to humans the world over.The disease caused by the fluke is called fasciolosis or fascioliasis, which is a
How Are They Different? 3. Describe The Stages In The Life Cycle Of The Human Liver Fluke, Clonorchis Sinensis. Fasciola gigantica is a parasitic flatworm of the class Trematoda, which causes tropical fascioliasis.It is regarded as one of the most important single platyhelminth infections of ruminants in Asia and Africa.Estimates of infection rates are as high as 80–100% in some countries. The infection is commonly called fasciolosis. The prevalence of F. gigantica often overlaps with that of Fasciola The sheep liver fluke (Fasciola hepatica) is a common parasite of sheep and cattle, which become infected by eating aquatic plants containing encysted metacercariae (juvenile flukes).
The secondary host is a snail. Ingest in larval stage from fish, fluke as cysts enter duodenum. Cysts reach intestine and hatch; flukes then move to the liver (biliary ducts).
