How do basidiomycetes reproduce?
Basidiomycota reproduce asexually by either budding or asexual spore formation. Asexual spore formation, however, most often takes place at the ends of specialized structures called conidiophores. The septae of terminal cells become fully defined, dividing a random number of nuclei into individual cells.
How do basidiomycetes reproduce sexually?
Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores.
Do Zygomycota reproduce sexually or asexually?
Zygomycota usually reproduce asexually by producing sporangiospores. Zygomycota reproduce sexually when environmental conditions become unfavorable. To reproduce sexually, two opposing mating strains must fuse or conjugate, thereby, sharing genetic content and creating zygospores.
Are zygospores asexual?
Order Mucorales. Asexual reproduction by multispored, few-spored or single-spored sporangia (sporangiola). Sexual reproduction by zygospores.
What are five typical basidiomycetes?
Five typical basidiomycetes are mushrooms, puffballs, stinkhorns, rusts, and smuts.
Where is Deuteromycota found?
land
Most deuteromycota live on land; they form visible mycelia with a fuzzy appearance called mold. Recombination of genetic material is known to take place between the different nuclei after some hyphae recombine.
What are five types of basidiomycetes?
Basidiomycetes include mushrooms, puffballs, rusts, smuts and jelly fungi.
Do basidiospores reproduce asexually?
The phylum Basidiomycota is a group of fungi characterized by the formation of specialized club-shaped cells, called basidia, during reproduction. The basidia normally produce four haploid spores, called basidiospores. Some Basidiomycota reproduce asexually, and some reproduce sexually.
Is Zygomycota harmful?
Zygomycetes are known to cause serious infections, articularly for diabetics and immunocompromised individuals. These infections can also occur as a result of major burns or other tramatic injury. One such disease is zygomycosis. This is a rare fungal disease that occurs in humans, and can even affect the fetus.
What disease can Zygomycota cause?
Cutaneous, gastrointestinal, and allergic diseases are also seen. The Mucorales are associated with angioinvasive disease, often leading to thrombosis, infarction of involved tissues, and tissue destruction mediated by a number of fungal proteases, lipases, and mycotoxins.
Why are there no zygospores?
A zygospore remains dormant while it waits for environmental cues, such as light, moisture, heat, or chemicals secreted by plants. When the environment is favorable, the zygospore germinates, meiosis occurs, and haploid vegetative cells are released.
