They are heterotrophic, multicellular organisms belonging to the Kingdom of Fungi.
They could be found on land, decaying matter, soil, and moist areas.
Fungi are subdivided into three main groups on the basis of their life cycles, the structure of their fruiting body, the arrangement of mycelium, and the type of spores (reproductive or distributional cells) they produce.
The three major groups of fungi are:
Molds: They are multicellular and filamentous. Example: Fusarium sp.
Mushroom: These are macroscopic filamentous fungi that bear large fruiting bodies. Example: Polyporus squamosus
Yeast: They are single-celled microscopic fungi. Example: Saccharomyces sp.
