Lactophenol cotton blue
What is the stain for molds?
Lactophenoyl Cotton Blue
What is rizopus stolonifer?
Looks like a ballon
What is hormodendrum?
Mold that also produces porospores and is very dark colored
What is penicillium notatum?
Mold that produces phailospores and looks like flower with dots stacked on dots
What is scopulariopsis?
Mold that produces porospores and looks like dots in a chain
Basidiomycota
Mushrooms, basidiospores, basidium where spores are held
What are candiospores?
Naked spores
What type of mold spores does Penecillum notatum produce?
Phaliospores
The first eukaryote to have its entire genome sequenced was the fungus Neurospora. Saccharomyces. Candida albicans. Rhizopus. Cryptococcus.
Saccharomyces
What does Rose Pickers disease cause?
Skins lesions and discolorization. If spread to respiratory tract difficult breathing
Zygomycota
Sporangiospores, zygospores, chitin and aseptate
What is rose pickers disease?
Sporothrix Schenckii
What is hyphae?
The branching, threadlike tubes that make up the bodies of multicellular fungi, and grow throughout what they are feeding on.
What does the hyphae make up?
The mycelium
What are Sporangiospores
They are formed within a sporangium, or sac, at the end of an aerial hypha called a sporangiophore. The sporangium can contain hundreds of sporangiospores. Such spores are produced by Rhizopus.
What colors do you see with Penecillum Notatum?
Top what you can see on foods would be the green blue fuzzy ring.
Diseases of animals caused by fungi are called mycoses.
True
Zygomycota produce zygosporangia, Ascomycota produce ascospores, and Basidiomycota produce basidiospores.
True
What is cycle B?
When larvae penetrates skin. Example would be Necator Americanus (Hook Worm)
What is cycle C?
When we ingest infected host such as meats. Cattle, pork, fish and more. Example would be Taenia Solium (tape worm)
What is the key difference between yeast and mold? Yeast have cellulose cell walls, while mold has chitin cell walls. Yeast is colonial, while mold is multicellular. Yeast is a fungus, while mold is an alga. Yeast is unicellular, while mold is multicellular.
Yeast is unicellular, while mold is multicellular.
What would you see if you looked at the bottom of Penecillum notatum?
Yellow folds that look like hills
Fungi and insects both use the nitrogenous polysaccharide ________ as a protective molecule in their outer surfaces.
chitin
What is zygomycota?
common mold it grows in the soil, decaying plant or animal material produces sporangiospores & zygospores aseptate hyphae
An unknown organism is a saprobe, gathers nutrients by absorption, lacks chlorophyll, has cell walls and is coenocytic. In which group is it most likely to be classified?
fungi
The ___________ include organisms classified as Deuteromycetes.
fungi
Candida albicans
mitosis -long filament-pseudohypha -test in serum and they produce a growing germ tube
The asexual spores of molds are classified according to their
mode of development.
What is Aspergillus?
mold that produces Philip spores & looks like firework trees
Hyphae are associated with ___.
molds
Molds are
multi-cellular- mycelia Vegetative hyphae- thallus (non-reproductive) Areia Hyphae-reproductive
The division Basidiomycota includes which of the following types of fungi? bread mold ringworm mushrooms truffles baker's yeast
mushrooms
The ________ is the entire interwoven mass of one multicellular fungal organism.
mycelium
What is the duteromycetes?
no known sexual spore all asxomyocata
What is Ascomycota/ basidiomycata?
sac fungi or ascomycetes they have separate hyphae. Basidiomycata is mushrooms basidiospores
Organisms such as fungi that absorb nutrients from dead organisms are called ________.
saprobes
What is vegetative hyphae?
secrete enzymes that break down complex cards
Most of the fungal species are classified into three divisions based on _____.
the type of sexual spore produced
What are phialospores?
these asexual naked spores are produced on specialized cells called sterigmata
Fungi yeasts
unicellular, reproduce asexually by budding, some produce sexual spores (Bakers Yeast)
The 4 fungi Divisions
zygomycota, ascomycota, basidiomycota and deuteromycetes
