ABSTRACT
Fungi are eukaryotic, spore-bearing achlorophyllous, heterotrophic organisms that generally reproduce sexually and asexually and who’s filamentous, branched somatic structures are typically surrounded by cell walls containing chitin or cellulose or both with many organic molecules and exhibiting absorptive nutrition. The organisms of fungi are the kingdom Fungi, the kingdom Chromista, and the kingdom Protozoa. The Zygomycota have sexual spores called zygospores which are formed by the union of two similar sex cells or gametes; the Oomycota have sexual spores called oospores formed from dissimilar gametes; the Chytriodiomycota have neither type of sexual spore; the Ascomycota have septate mycelium and sexual spores in asci; the Basidiomycota have septate mycelium, frequently with clamp connections, and sexual spores. The protozoa have thalli as a motile mass of protoplasm which is transformed into a mass of small, aseptate resting spores that on germination form motile cells with or without flagella.
