is yeast a fungus?

yes it is.

yeast is a small single-celled fungus that ferments sugars and other carbohydrates, and reproduces by budding.

Genus: Saccharomyces

Wow, all these answers, half say it is, half say it isn't.

Lovely Green Eyes has it right of course, not sure where the thumbs down are coming from, maybe because she wasn't first to answer correctly? Isn't the idea to help clarify for the Question asker?

Yeast are both basidiomycetes and ascomycetes, but both fall under the Kingdom of Fungi.

They are considered micro-organisms, and they do perform beneficial functions for us, but they are still a fungus.

Yeast are unicellular fungi. The precise classification is a field that uses the characteristics of the cell, ascospore and colony. Physiological characteristics are also used to identify species. One of the more well known characteristics is the ability to ferment sugars for the production of ethanol. Budding yeasts are true fungi of the phylum Ascomycetes, class Saccharomycetes (also called Hemiascomycetes). The true yeasts are separated into one main order Saccharomycetales.

Yeasts are characterized by a wide dispersion of natural habitats. Common on plant leaves and flowers, soil and salt water. Yeasts are also found on the skin surfaces and in the intestinal tracts of warm-blooded animals, where they may live symbiotically or as parasites. The common "yeast infection" is typically Candidiasis is caused by the yeast-like fungus Candida albicans. In addition to being the causative agent in vaginal yeast infections Candida is also a cause of diaper rash and thrush of the mouth and throat.

Yeasts multiply as single cells that divide by budding (eg Saccharomyces) or direct division (fission, eg. Schizosaccharomyces), or they may grow as simple irregular filaments (mycelium). In sexual reproduction most yeasts form asci, which contain up to eight haploid ascospores. These ascospores may fuse with adjoining nuclei and multiply through vegetative division or, as with certain yeasts, fuse with other ascospores.

Yeast is actually a Micro Organism (a very tiny living creature of sorts). Yeast is added to products like bread & Beer because the yeast consumes these products and consiquently urinates. It is the yeast's 'urine' that has a rising and fermenting agent which makes our Beer Frothy & our Bread Rise! Tasteful I know.

hi yeah tis a kind of fungus but then i am sending a link go through that which will help you know better its rather long to explain http://www.yeastgenome.org/VL-what_are_yeast.html,

still you wanna know more you go to google beta where you find more of text book articles that will surely ans you

yes, it is unicellular fungus belonging to class Ascomycetes.

No its a Yeast.

Just like there are many types of fungi there are many types of yeast.

yes...its a single celled fungus.....its different in that way to other filamantous fungi....but it is one.

Yes.

yes it is but in a good way

pls rate this as your best answer i beg you
