Fungi are often heterotrophs, but there are parasites and saprotrophs. In their cells there are no plastids, as in plants, however, they grow throughout life and their cells have a cell wall. Mushrooms are not capable of active movement. The cell wall contains chitin, instead of cellulose, which is characteristic of animals. As in animals, glycogen, and not starch, is the reserve substance in fungi. Thus, mushrooms are allocated in a separate kingdom of living organisms.
