Question

On the basis of mycelium, mode of spore formation and fruiting bodies from 4 divide kingdom into 4 classes and explain general characteristic.​

Answer 1

Answer:

Kingdom Fungi are classified into the following based on the formation of spores:

Zygomycetes : These are formed by the fusion of two different cells. The sexual spores are known as zygospores while the asexual spores are known as sporangiospores. The hyphae are without the septa.

Ascomycetes : They are also called as sac fungi. They can be coprophilous, decomposers, parasitic or saprophytic. The sexual spores are called ascospores. Asexual reproduction occurs by conidiospores. Example: Saccharomyces

Basidiomycetes :Mushrooms are the most commonly found basidiomycetes and mostly live as parasites. Sexual reproduction occurs by basidiospores. Asexual reproduction occurs by conidia, budding or fragmentation.

Example: Agaricus

Deuteromycetes: They are otherwise called imperfect fungi as they do not follow the regular reproduction cycle as the other fungi. They do not reproduce sexually. Asexual reproduction occurs by conidia.

Example:Trichoderma.
