Deuteromycota asexual reproduction definition


The kingdom Fungi is divided into four phyla: Zygomycota, Ascomycota, Basidiomycota, and Deuteromycota imperfect fungi. The way these phyla are differentiated is based on the way in which fungi reproduce. The phylum zygomycota contains about different species.

It is named after a thick-walled structure that is formed during reproduction. A typical example this phylum is Rhizopus black bread mold.

Zygomycetes can develop both sexually and asexually. A zygote is formed through the fusino of hypae, and meiosis occurs just before germination.

Asexual forms (anamorph) were often...

There are over 30, species of this phylum. Most of these are saprotrophs that are involved with ecology because they digest materials that are not easily decomposed. Typical examples of ascomycetes are yeasts, truffles, and morels. They develop sexually by the fomation of ascospores inside a sac called an ascus. Asexual reproduction can also occur. There are approximately 16, living species of this type of fungi.

Examples are toadstools, mushrooms, and rusts.

Sexual reproduction is more Deuteromycota asexual reproduction definition than asexual. Sexual reproduction happens through basidiospores being born on basidia, club-shaped structures.

There are about 17, different species of imperfect fungi. Penicillium is an example of this see picture below. From observation, imperfect fungi do not reproduce sexually. Because of this, some do not consider imperfect fungi as a separate phylum. They are thought to be ascomycetes who have lost the ability to reproduce sexually. For a general overview of classification, including a fungal phylogenetic tree and illustrated life cylce, see this Classification Lab.

The Phylum Chytridiomycota (chytrids) is one of the five true phyla of fungi. Zygomycota, a small group in the fungi kingdom, can reproduce asexually or sexually, Most species are saprobes meaning they live off decaying organic material.

The last group of fungi we will be discussing is the Deuteromycota. With the exception of one group, all members reproduce by means of special spores known as Ascomycetes for which sexual stage and asexual stages are not associated.

It is named after a thick-walled structure that is "Deuteromycota asexual reproduction definition" during reproduction.
