The most common trematode is the liver fluke fasciola hepatica. Fig: diagram of liver fluke. 4.4.2 Life cycle of fasciola Hepatica (Liver Fluke) The adult lives in the bile duct of its primary host. This could be sheep, goat, cattle and occasionally humans. The adult lays egg which passes out in the host feces.
Tapeworms (Cestoda) are a highly diversified group of ubiquitous endoparasites that generally have a two-phase life cycle: vertebrates serve as final hosts and all orders may utilize arthropods, other invertebrates or even vertebrates as first intermediate hosts with the sole exception of the Caryophyllidea, whose eggs only infect oligocheate annelids. Flukes, like other parasitic flatworms, have complex life cycles often involving two or The mostly free-living Turbellaria include the planarian, Dugesia, shown above The Cestoda, or tapeworms, are intestinal parasites in vertebra flatworms or "solid worms" belong to which phylum? tapeworms, parasitic Commonfreshwater (streams and lakes) planarians of North America are an (8 steps)) Adult fluke 1-2 cm long lives in bile ducts of liver in human The Phylum: Platyhelminthes includes the flatworms (Planaria, flukes & tapeworms) Three Classes treated here are Turbellaria, Trematoda and Cestoda. The phylum name Platyhelminthes literally means "flatworms.
Phylum platyhelminthes 1. FLATWORMS Kingdom Animalia Phylum Platyhelminthes Ex. Planaria, flukes and tapeworms Class Cestoda Class Turbellaria Class Trematoda 2. Characteristics of Platyhelminthes • Body symmetery: bilateral • Body organization: triploblastic (3 layers) – Ectoderm – Mesoderm (first!!) They live in an aquatic environment (freshwater or marine) or on moist soil. Both tapeworms and flukes are internal parasites that inhabit a host’s tissues, cavities in body organs, or blood vessels.
Phylum Platyhelminthes The Flatworms Phylum Platyhelminthes About 20,000 species About 80% of parasites are from this phylum Divided into three major groups Free-living flatworms Parasitic tapeworms Parasitic flukes Flatworms Range in size Some microscopic free-living forms Parasitic forms over 20 meters long Show many advances over Cnidaria General Characteristics The following
state the phylum to which liver fluke and planaria belongs - Science - Diversity in Living Organisms. state the phylum to which liver fluke and planaria belongs.
Phylum Platyhelminthes The flatworms include more than 13,000 species of free-living and parasitic species. There are 3 classes of flat-worms, the planarians, flukes and tapeworms. General Physical Traits (Anatomy): Flatworms are bilaterally symmetrical. This means that they can only be cut them length-wise to produce two mirror-image halves.
They belong to class turbellaria. On the other hand, tapeworms are segmented flatworms which are parasitic and live in the intestines of animals. Like all flatworms, planaria belong to the Kingdom Animalia, and the Phylum Platyhelminthes. This phylum also contains parasitic flatworms, like the tapeworm and the liver fluke. Free-living flatworms like the planaria are grouped into the Class Turbellaria. The most common species studied in the lab is the brown planaria, Dugesia. This is why they are called names such as Tapeworm, Flatworm, Fluke and Planarian.
On the other hand, tapeworms are segmented flatworms which are parasitic and live in the intestines of animals. They belong to class Cestoda. Platyhelminthes are mostly worm-like creatures that are dorsoventrally flattened, meaning they look like a ribbon. This is why they are called names such as Tapeworm, Flatworm, Fluke and Planarian.
So, the correct answer is option B. Phylum Platyhelminthes The flatworms include more than 13,000 species of free-living and parasitic species.
There are also a great many flatworms that are parasites. These fall into two classes - the Trematoda, or "flukes", and the Cestoda, or "tapeworms". Tapeworms are intestinal parasites in vertebrate animals.
