* Heterotrophic: They obtain nutrients from organic matter, meaning they cannot produce their own food like plants do.
* Eukaryotic: They have cells with membrane-bound nuclei and organelles.
* Chitinous cell walls: Their cell walls are made of chitin, a strong and flexible polysaccharide.
* Saprotrophic or parasitic: They obtain nutrients by decomposing organic matter (saprotrophic) or by living on and absorbing nutrients from a living host (parasitic).
* Reproduce through spores: They produce spores, which are tiny reproductive cells that can survive in harsh conditions and disperse easily.
* Multicellular (except for yeasts): Most fungi are multicellular organisms composed of hyphae, thread-like structures that form a network called mycelium.
