To differentiate : Between the body plan of nematodes and annelids. Concept introduction : The basic difference in the body plan of nematode and annelid is that the annelids are eucoelomate (having true coelom). On the other hand, the nematodes are pseudocoelomates (having false coelom). The annelids show true segmentation unlike nematodes. The nematodes are mostly parasitic. On the other hand, only some annelids are parasitic.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
