Explanation:

Parasitic worms, also known as Helminths, are eukaryotic multicellular parasites. These parasites produce certain molecules that help them to enter into the tissues of the host cell.

Example of a parasitic worm is the larval form of Schistosoma mansoni parasite. The larval form of this parasite is known as miracidium. The miracidium causes schistosomiasis or snail fever.
