The zygomycetes are a relatively small group of fungi belonging to the Phylum Zygomycota. They include the familiar bread mold, Rhizopus stolonifer, which rapidly propagates on the surfaces of breads, fruits, and vegetables. Most species are saprobes, living off decaying organic material; a few are parasites, particularly of insects.

Apr 18, 2019 · Yeasts - Phylum Ascomycota—Sac Fungi Yeast is used in the making of alcohol, is used in baking industries to make bread, and is used in the synthesis of protein, fat, vitamins and enzymes. Bread Mold - Phylum Zygomycota --- Molds Bread mold , a decomposer , plays a key role in the carbon cycle .
Rhizopus Stolonifer or bread mold is a part of the Phylum Zygomycota and it plays a role in the carbon cycle by decomposing soil , dung , and many types of foods . It is also used to manufacture medicines more specifically pregnancy pills .
Common black bread mold; a representative zygomycte Phylum Ascomycota: Sac Fungi Think beer, baking bread (yeast), morels, and trufels: produce spores in the ascus (a sac) which develops as a result of sexual reproduction; the female gametangium, the ascognium, is fertilized by male nuclei from antheridia; includes the penicillium that reproduces sexually
Aug 25, 2020 · PHYLUM ZYGOMYCOTA: Conjugation Fungi All members of the Zygomycetes produce a thick-walled zygote, known as a zygosporangium. Most fungi in this division are saprophytes, including the common black bread mold, Rhizopus. Before the introduction of chemical preservatives into bread, Rhizopus was an almost certain invader, especially if the …
Imperfect fungi—those that do not display a sexual phase—are classified in the form phylum Deuteromycota. Deuteromycota is a polyphyletic group where many species are more closely related to organisms in other phyla than to each other; hence it cannot be called a true phylum and must, instead, be given the name form phylum. Since they do not possess the sexual structures that are used to classify other fungi, they are less well described in comparison to other divisions. Most members live on land, with a few aquatic exceptions. They form visible mycelia with a fuzzy appearance and are commonly known as mold. Molecular analysis shows that the closest group to the deuteromycetes is the ascomycetes. In fact, some species, such as some Aspergillus, which were once classified as imperfect fungi, are now classified as ascomycetes.
The five true phyla of fungi are the Chytridiomycota (Chytrids), the Zygomycota (conjugated fungi), the Ascomycota (sac fungi), the Basidiomycota (club fungi) and the recently described Phylum Glomeromycota. The Deuteromycota is an informal group of unrelated fungi that all share a common character – they use strictly asexual reproduction.
Zygomycota: The Conjugated Fungi. The zygomycetes are a relatively small group of fungi belonging to the Phylum Zygomycota. They include the familiar bread mold, Rhizopus stolonifer, which rapidly propagates on the surfaces of breads, fruits, and vegetables.
The majority of known fungi belong to the Phylum Ascomycota, which is characterized by the formation of an ascus (plural, asci), a sac-like structure that contains haploid ascospores. Many ascomycetes are of commercial importance.
The best-known fairy ring fungus has the scientific name Marasmius oreades. The body of this fungus, its mycelium, is underground and grows outward in a circle.
The kingdom Fungi contains five major phyla that were established according to their mode of sexual reproduction or using molecular data. Polyphyletic, unrelated fungi that reproduce without a sexual cycle are placed for convenience in a sixth group called a “form phylum.”. Not all mycologists agree with this scheme.
The only class in the Phylum Chytridiomycota is the Chytridiomycetes. The chytrids are the simplest and most primitive Eumycota, or true fungi. The evolutionary record shows that the first recognizable chytrids appeared during the late pre-Cambrian period, more than 500 million years ago.
