What do zygomycota eat

They are thought to be the most primitive terrestrial fungi. It is believed that Zygomycota emerged between and 1, million years ago. It is suggested that Zygomycota are either para- or polyphletic, but this has yet to be determine.

They share many characteristics with flagellated fungi, and therefore were once thought to be related to acquatic fungi. However, differences in cell-wall structure and a lack of flagellated spores or gamets indicate that there is no relation.

Zygomycota is a classification that encompasses many different species with very different genome structures. Cell walls are composed of chitin-chitosan. The mature zygospore has thick walls. Zygomycota also have coenocytic mycelium. They normally grow as mycellia or as filaments of long cells.

Hyphae typically lack cross walls or septa, and therefore are coeonocytic. It is believed that zygomycota have zygotic or haplontic life cycles. Zygomycota are able to reproduce both sexually and asexually. In fact, sexual reproduction via zygospores following gametangial fusion is a definitive characteristic of Zygomycota. Sexual reproduction is haploid-dominant, while asexual reproduction makes use of aplanospores.

In Zygomycota, sexual reproduction is the fusion of undifferentiated isogametangia or anisogametangia. Mating strains progametangia grow toward each other and induce the hormone trisporic acid to intiate sexual development.

This fusion produces a zygote, which develops into a zygospore. The way Zygomycota reproduce asexually is also distinctive. With asexual reproduction, asexual spores called sporangiospores are produced in sporangia. Typically, three sporangia are produced, but there are variations within asexual reproduction. Zygomycota are also pathogens for animals, amebas, plants, and other fungi. Does Zygomycota move? What do most zygomycetes feed on?

Sexual reproduction by zygospores. Basidiomycota reproduce asexually by either budding or asexual spore formation. Budding occurs when an outgrowth of the parent cell is separated into a new cell.

Any cell in the organism can bud. Asexual spore formation, however, most often takes place at the ends of specialized structures called conidiophores. Zygomycetes have asexual and sexual phases in their life cycles. In the asexual phase, spores are produced from haploid sporangia by mitosis not shown. In the sexual phase, plus and minus haploid mating types conjugate to form a heterokaryotic zygosporangium. Karyogamy then produces a diploid zygote.

A sporangium can be globose to obovoid or flask- or dumbbell-shaped to somewhat cylindrical in a few taxa. Its outer wall can be smooth, have terminal spines, or be covered with calcium oxalate crystals or spines, and at maturity it can deliquesce, persist, or become evanescent, depending on the species. Home General Questions What does Zygomycota eat? The affectionate couple at left are two sporangia of Rhizopus domesticus arising from a small nest of rhizoids. The root-like rhizoids help the sporangia to remain anchored to whatever object they may encounter.

The thread extending to the right and down is a stolon, a hypha that grows out until it encounters another appropriate place to attach rhizoids and build sporangia. Stolons, rhizoids and sporangia all characterize the genus Rhizopus. The sporangia should contain spores, but they are either still immature or, more likely, have already dispersed their spores and remain now only as sporangiophores the stalks and columellae the swollen apical parts.

The smaller picture immediately to the left is of a single sporangium, also of Rhizopus domesticus. It is easy to see here that the spherical sporangium contains a large number of spores.

But look more closely: inside you will see the very faint outline of the balloon-like columella extending into the spore mass. When the sporangial wall breaks, as it had done with the couple at far left, nothing is left but the columella and a few spores that were left behind. This is the normal type of sporangium as seen in Rhizopus, Mucor, Absidia, Circinella and other members of the family Mucoraceae.

If you attempt to grow fungi in petri dishes you will soon encounter members of the Mucoraceae. They are found everywhere and are invasive and aggressive. Zygomycetes are interesting fungi that are able to hold their own in the face of competition from members of the much larger Dikarya. They are characterized by several features that set them apart.

First of all their hyphae are coenocytic, meaning that they have no septa. With no cross-walls to slow the flow of cytoplasm these organisms can extend their hyphae rapidly into new territory.

They do not respond as well as the Dikarya to cellulose, sucrose and other common plant products and instead often seem to associate with materials of animal or fungal origin. They can be strong digesters of protein and even chitin, the fundamental material of insect exoskeletons and fungal hyphae. Although the phylum is not large it is quite diverse. Several orders have been recognized. Many, such as the Mucorales discussed above appear to be saprotrophic and to respond most vigourously to simple sugars, such as glucose, and to amino acids and proteins.

Other orders are characterized mainly by parasitic forms attacking fungi and animals. None appear to be parasites of plants, although Endogone pisiformis seems to be restricted to living mosses.

Rhizopus species and many Zygomycota produce sporangia with brittle walls and dry spores. When they are mature any air movement may be sufficent to carry the spores away to a new location.

This is why Rhizopus species are a great pest in the laboratory. On the other hand many other Zygomycota, such as Absidia caerulea at right, maintain their sporangiospores in droplets of liquid.
