A ) - Chytridiomycota or the Chytrids( this fungi has only one class- Chytridiomycetes) : Primitive of all fungi
· One group has cellulose and chitin in cell wall, while others contain only chitin
· Mostly unicellular though some may form multicellular organisms
· Some live in aquatic environment while some also live in land
- Ascomykota or the Sac Fungi : Forms a sac shaped structure known as ascus which is contains haploid ascospores
· Yeasts belong to this category and are used in baking purposes like many others belonging to this phylum
· Humans, animals and plants can be their hosts
· Asexual reproduction is common and frequent
· Yeasts produce through the process of budding
- Basidiomycota or the Club Fungi : They contain spores present in a spore case called basidium. These spore cases are generally shaped like a club.
· A large number of spore production takes place.
· Spores hardly mature or germinate
· Alternation of generation is observed in their lifecycle
- Zygomycota or the Conjugated Fungi : Multiply very rapidly on breads
· They are mostly saprobes, i.e. they get their nutrition from organic material which is decaying
· Parasites to mostly insects
· Contains a thallus of the coenocytic hyphae
· Unfavourable conditions leads to sexual reproduction
- Glomeromycot (a recent addition to mycology) : Mostly associated with tree roots
· No sexual reproduction takes place
· Will not survive without roots of plants
· Has a monophyletic lineage, that is , they all come from a common ancestor
B) Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaebacteria, eubacteria, and protists. Many plants and fungi reproduce asexually as well.
