Is Allomyces a Chytridiomycota?
Some examples of the Chytridiomycota are Allomyces, a water mold, Synchytrium endobioticum, a pathogen of potato, and Neocallimastix, a chytrid that lives symbiotically in the gut of herbivores, such as cattle.
What does the scientific name Allomyces Macrogynus represent?
Allomyces macrogynus is a member of the Chytridiomycetes (Blastocladiales). The Chytridiomycetes represent one of the four classes of the Eumycota (“true fungi”) and contain the most ancestral fungal lineages (“lower fungi”), namely Blastocladiales, Chytridiales, Monoblepharidales and Spizellomycetales.
Is Allomyces unicellular or multicellular?
There is some controversy about the placement of certain fungi into the Chytridiomycota, and there is some evidence to support that the multicellular forms, such as Allomyces and other members of the Blastocladiales, should be placed in a new phylum, the Blastocladiomycota.
What is Basidium ascus and zygotes?
It is a sac-like structure which contains sexual spores of ascomycetes. Ascus is developed within the mycelium and is a microscopic structure. Ascus usually produces eight ascospores internally by two meiotic cell divisions of the diploid zygote. Basidium is a sexual spore-bearing cell produced in basidiomycetes fungi.
What is Allomyces scientific name?
Allomyces arbusculus (Aquatic fungus)
Where does Allomyces get its nutrients?
Saprotrophic fungi obtain their food from dead organic material and are ecologically useful decomposers. Parasitic fungi feed on living organisms (usually plants), thus causing disease. To feed, both types of fungi secrete digestive enzymes into the nutritive surface on which they are growing.
How is Chytridiomycota classified?
Chytridiomycota are a division of zoosporic organisms in the kingdom Fungi, informally known as chytrids. The name is derived from the Ancient Greek χυτρίδιον (khutrídion), meaning “little pot”, describing the structure containing unreleased zoöspores.
Why is Chytridiomycota important?
Because Chytridiomycota often feed on decaying organisms, they are important decomposers. While this is an important function, Chytridiomycota can also have a negative impact on human produce, particularly Synchytrium endobioticum, the species that causes potato wart.
How does a basidium compare to an ascus in the way the spores are produced and the number of spores produced?
– A basidium produces sexual spores externally and is most often found on a larger fruiting body called the basidiocarp. They produce heaps of spores. – An ascus is a sac-like structure that produces sexual spores. These structures typically produce only eight spores (ascospores)—much fewer than the basidia.
What is a whole fungal organism called?
A mass of hyphae make up the body of a fungus, which is called a mycelium (plural, mycelia).
What is the classification of Zygomycota?
ZygomycotaZygomycota / Scientific name
Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla the Mucoromycota and Zoopagomycota. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material.
What is zygomycetes method of movement?
Transmission can be done by wet or dry. That means they have the ability to use both air currents and water droplets. Other methods include mechanical transport, such as movement while settled on the fur of animals. Spores from Zygomycetes are often quite large so they settle on surfaces quite easily.
What is basidium ascus and zygotes?
What is specific about Chytridiomycota?
The Chytridiomycota, often called chytrids, are unique among all fungi in having motile stages in their life cycles; no other fungi have this trait. These motile stages take the form of zoospores, single cells with a single posterior (at the rear) flagellum.
What is ascus and basidium?
The ascus is a sac-like structure that bears reproductive cells. These cells produce sexual spores. Basidium is a club-shaped structure having sexual cells that produce sexual spores.
