The characteristics of organisms in the Fungi kingdom include:
- Decomposers or parasites
- Heterotrophic
- Cell walls of chitin
- Can be unicellular or multicellular
Fungi are heterotrophic organisms that obtain their nutrients by decomposing organic matter or by being parasites. Their cell walls are made of chitin, and they can exist in both unicellular (like yeasts) and multicellular forms (like molds and mushrooms). Fungi are not autotrophic; they do not have cell walls made of cellulose (which is found in plants), nor are they made of multiple types of tissue as seen in more complex multicellular organisms.
