In Basidiomycetes, asexual spores are generally not found. Vegetative reproduction by fragmentation is common, while sexual reproduction ultimately results in the formation of basidiospores.

Phycomycetes reproduce asexually by motile zoospores or non-motile aplanospores. These spores are produced endogenously within a sporangium.

Prions are infectious agents consisting of abnormally folded protein, not DNA. They are associated with neurological diseases such as bovine spongiform encephalopathy, commonly called mad cow disease.

Methanogens occur in the gut of ruminants such as cows and buffaloes. They are responsible for producing methane, or biogas, from the dung of these animals.

Mycoplasma completely lacks a cell wall and includes the smallest living cells known. These organisms can also survive without oxygen, and many are pathogenic in animals and plants.

Cyanobacteria are prokaryotic members of Kingdom Monera and therefore do not possess a well-defined nucleus. Some forms, such as Nostoc and Anabaena, fix atmospheric nitrogen in specialised cells called heterocysts.

Archaebacteria occur in harsh habitats such as extremely salty areas, hot springs and marshy areas. Their different cell wall structure supports survival under these conditions.

A cell wall is completely absent in Mycoplasma, which includes the smallest living cells known.

The organism belongs to Kingdom Fungi. Fungi are absorptive heterotrophs, their walls contain chitin and other polysaccharides, and their reserve food is stored as glycogen and oil droplets.

Mycoplasma completely lack a cell wall. They are the smallest living cells known, can survive without oxygen and include forms that cause diseases in plants and animals.

Kingdom Protista includes single-celled eukaryotes with well-defined nuclei and membrane-bound organelles. Sexual reproduction in protists involves cell fusion followed by the formation of a zygote.
