What is the difference between Cestodes and nematodes?
What is the difference between Cestodes and nematodes?
The key difference between Nematodes and Cestodes is that Nematodes are roundworms whereas Cestodes are flatworms. The kingdom Animalia is comprised of several phyla. Phylum Platyhelminthes includes worms that are flattened dorsoventrally and acoelomates. Cestoda is parasitic worm class of phylum Platyhelminthes.
What is unique about cestoda?
Cestodes, commonly called tapeworms, are the taxonomic class of Cestoda, which are parasitic worms. They have a tape-like and segmented body. These animals are hermaphroditic, lack a digestive tract, and do not have a body cavity.
How are nematodes different from flatworms?
Like the flatworms, nematodes are bilaterally symmetrical. They take their name from their round body cross-sectional shape. Unlike the flatworms in which food and waste enter and exit from the same opening, nematodes have a complete digestive system.
What is the difference between a Platyhelminth and a nematode?
Nematodes are called roundworms while Platyhelminthes are called flatworms. Nematodes are pseudocoelomates, while Platyhelminthes are acoelomates. Species of nematodes are higher than that of Platyhelminthes. Platyhelminthes have an incomplete gut whereas nematodes have a complete one.
Why the macroscopic worms Trematodes Cestodes and nematodes are included in the study of microbiology which implies microscopic organisms?
Key Concepts and Summary Helminth parasites are included within the study of microbiology because they are often identified by looking for microscopic eggs and larvae. The two major groups of helminth parasites are the roundworms (Nematoda) and the flatworms (Platyhelminthes).
What is the mode of life of cestoda?
All cestodes cycle through 3 stages—eggs, larvae, and adults. Adults inhabit the intestines of definitive, or final, hosts, which are mammalian carnivores, including humans. Several of the adult tapeworms that infect humans are named after their main intermediate host (the fish, beef, and pork tapeworms).
What are two differences between flatworms and roundworms?
Note: Both flatworms and roundworms can be parasitic or free living….What is the difference between flatworms and roundworms?
| Flatworms | Roundworms |
|---|---|
| They have a thin, dorsoventrally flattened body, so called flatworms. | They have a long cylindrical body, vermiform, unsegmented with no lateral appendages. |
What are some major differences between roundworms and flatworms?
A flatworm has a thin, dorsoventrally flattened body. Roundworms are more cylindrical in shape and tapered to a fine point at one end. Similarly, roundworms have a rigid outer covering called a cuticle that they shed repeatedly throughout their lives and as they grow.
What is the difference between Annelida and Arthropoda?
Annelida and Arthropoda are two phyla of the kingdom Animalia. Both Annelida and Arthropoda are composed of segmented animals. The main difference between Annelid and Arthropoda is that Annelida consists of a hydrostatic skeleton whereas Arthropoda consists of an exoskeleton made up of chitin.
What are the main differences between the Cnidaria and the Platyhelminthes phyla?
Cnidarians are diploblastic, whereas Platyhelminthes are triploblastic. Platyhelminthes possess bilaterally symmetrical, soft, worm-like elongated bodies, whereas cnidarian possess radially symmetrical, soft, medusa-like or polyp-like body forms. Cephalization is present in Platyhelminthes, but not in cnidarians.
What is the difference between a cestode and a nematode?
Cestodes have a long, ribbon-like, dorsoventrally flattened body while nematodes have a cylindrical body tapered at each end. Cestodes have a neodermal cuticle called tegument while nematodes have a thick, collagenous cuticle. Cestodes are multisegmented worms while nematodes are unsegmented worms.
What is the classification of Cestoda?
Cestoda is a class of phylum Platyhelminthes of Kingdom Animalia. Cestodes are parasitic flatworms or tapeworms. Cestodes are obligate parasites in the gut of vertebrates. They are bilaterally symmetrical, and they are triploblastic.
What is the phylum of Nematoda?
Nematoda is a phylum of Kingdom Animalia that comprises of cylindrically shaped worms or the round worms. Nematodes are bilaterally symmetrical, long and thin, hair like worms. They are triploblastic and have a short body cavity (pseudocoelom) that is not a true coelom.
What is the difference between a cestode and a trematode?
One of the other big differences between cestodes and trematodes is the fact that unlike cestodes, trematodes have a digestive tract that runs from the oral cavity to the esophagus where it’s then divided into the bilateral ceca. As such, it’s able to consume food material through the oral cavity and digest them.
