Flagellum ==> Protists
Mycelium is the vegetative organism of mushrooms.
A heterotroph is an organism that needs food of organic origin, and this is the case of protists and fungi.
Pseudopods are cytoplasmic extensions of protozoa used for movement and prehension.
Chitin is a nitrogenous substance contained in the cuticle of insects and fungi.
