The adaptive benefit of filamentous nature of fungal mycelia. Introduction : The species of fungi grow as filaments and as yeasts, but majority of the species grow as filaments and few grow as yeasts. The bodies of these fungi form a filamentous structure, called hyphae. The hyphae forms an “interwoven mass”, called as mycelium, which pierces the material on which the fungus feeds. There are some fungi, which have modified hyphae, called haustoria which play a role in extracting nutrients from the plants.

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.
