Adaptation of platyhelminthes

Answer 1

The Platyhelminthes have developed several adaptations. Body covering, organs of adhesion, organs of locomotion, organs of nutrition, Neurosensory system, and their reproductive system are a few.

Answer 2

Platyhelminthes, or flatworms, demonstrate various adaptations. Their flat shape makes it easier for oxygen to reach cells and for waste to be removed without a complex circulatory system. Perhaps their most interesting adaptation is the ability to regenerate, which aids the survival of the individual and can also be used for asexual reproduction. Some flatworms have adapted to a parasitic lifestyle, such as evolving hooks on their mouths that let them attach to a host's body.

Answer 3

Characteristics of Platyhelminthes:-

1)Bilaterally symmetrical.

2)Body having 3 layers of tissues with organs and organelles.

3)Body contains no internal cavity.

4)Possesses a blind gut (i.e. it has a mouth but no anus)

5)Has Protonephridial excretory organs instead of an anus.

6)Has normally a nervous system of longitudinal fibres rather than a net.

7)Generally dorsoventrally flattened.

8)Reproduction mostly sexual as hermaphrodites.

9)Mostly they feed on animals and other smaller life forms.

10)Some species occur in all major habitats, including many as parasites of other animals.

Answer 4

covered by protective tegument which is specialized body covering resistant to digestive juice

produce large no of eggs

anterior end with hooks or suckers for attachment to the host

well developed reproductive system helps ensure transmission to the host

Answer 5

Flatworms have many adaptations as an internal parasite. Their body is covered by a protective tegument which makes it resistant to digestive acids. They release a large number of eggs, which ensures that some survive to reinfect or pass on the infection, and they have attachment features on their anteriors to remain attached to their host.

Answer 6

Platyhelminthes have adapted to a parasitic lifestyle in various environments, including aquatic and terrestrial ecosystems. They have developed specialized structures for attachment and feeding, such as suckers and hooks. Many species have complex life cycles involving multiple hosts to ensure successful reproduction and survival. Additionally, some flatworms have evolved the ability to regenerate lost body parts as a defense mechanism against predators.

Answer 7

presence of hooks and cuticle body
