This is the study of Fungi
Mycology
Fungi constitute an extremely diverse group of organisms and are generally classified as________________
Molds or yeasts
Fungi’s They are prokaryotic
False, they are eukaryotic
Fungi’s They have no nuclei and mitochondria
False, they have a nuclei and mitochondria
Fungi’s They are not heterotrophs
False, they are heterotrophs
Fungi’s They do photosynthesis and have a chlorophyl
False, they do not photosynthesis and chlorophyl
Fungi’s They depend on other organisms to survive
True
Fungi’s They are multicellular
True
Fungi’s They can move on their own
False, They cannot move on their own
This is a species of yeast. It is perhaps the most useful yeast, having been instrumental to winemaking, baking, and brewing since ancient times.
Saccharomyces cerevisiae
This is olive green and thrives on plants in particular, but can also grow on household surfaces like walls, cabinets, and carpets.
Cladosporium
This is the mold that typically grows on spoiled food like bread. It can also grow on nutrient-poor but moisture-rich environments like the basement.
Aspergillus
Is famous for its antibacterial properties and is usually bluish-green. However, it can also emits mycotoxins that are toxic to both people and pets. They prefer colder environments like soil, but some also form on wet items in the home
Penicillium
The plant body of the true fungi
thallus
Most fungi are multicellular and are composed of long filaments
Hyphae
All hyphae in a particular fungus from an interwoven mass
Mycelium
This is above ground, reproductive structure produced by fungi
Fruiting body
What are the three types of Mycelium?
Vegetative, Aerial, and Fertile
This is a type of Mycelium that penetrate the surface of the medium and absorb nutrients.
Vegetative Mycelium
This is a type of Mycelium that grow above the agar surface
Aerial Mycelium
This is a type of Mycelium that bear reproductive structures such as conidia or sporangia.
Fertile Mycelium
A fungi that possess melanin pigments in their cell wall
Phaeoid
Those hyphae that do not possess any pigment in their cell wall
Hyaline
The fungi obtain their nutrition by feeding on dead organic substances
Saprophytic
The fungi that obtain their nutrition by living on other living organisms (plants or animals) and absorb nutrients from their host.
Parasitic
These fungi live by having an interdependent relationship with other species in which both are mutually benefited
Symbiotic
These are spores that are formed by the fusion of two different cells.
Zygomycetes
These are sexual spores in the Zygomycetes
Zygospores
These are asexual spores in the Zygomycetes
Sporangiospores
These are also known as sac fungi. They can be coprophilous, decomposers, parasitic or saprophytic
Ascomycetes
These are the sexual spores of ascomycetes
Ascospores
These are the asexual spores of ascomycetes
Conidiospores
Mushrooms are the most commonly found in them and mostly live as parasites
Basidiomycetes
These are the sexual spores of Basidiomycetes
Basidiospores
These are the asexual spores of Basidiomycetes
Conidia, budding or fragmentation
They are also called as imperfect fungi as they do not follow the regular reproduction cycle as the other fungi.
Deuteromycetes
This is the asexual reproduction of deuteromycetes
conidia
This is an infectious microbe consisting of a segment of nucleic acid (either RNA or DNA) surrounded by a protein coat. A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.
Virus
What is a Bacteria?
Living organism, unicellular, one cell
Larger (1000nm)
In Latin means, Little Sticks
Usually treated with antibiotics
What is a virus?
Not living, no cells
Smaller (20-300nm)
In Latin means, Poison
Antibiotics will not effect the disease
What are the types of Viruses?
Helical Viruses
Polyhedral Viruses
Spherical Viruses
Complex Viruses
This is a type of bacteria that looks like a tobacco mosaic virus, which infects a number of different types of plants, have a slinky shaped capsid that twists around and encloses its genetic material.
Helical Viruses
This is a type of bacteria that just like the adenoviruses, which are known to cause a range of illnesses from pink eye to pneumonia, are composed of genetic material surrounded by a many-sided capsid, usually with 20 triangular faces.
Polyhedral viruses
This is a type of bacteria just like the infamous coronavirus, are essentially helical viruses enclosed in a membrane known as an envelope, which is spiked with sugary proteins that assist in sticking to and entering host cells.
Spherical Viruses
This is a type of bacteria just like bacteriophages, which infect and kill bacteria, resemble a lunar lander, and are composed of a polyhedral “head” and a helical body (or “tail sheath”) and legs (or “tail fibers”) that attach to a cell membrane so that it can transfer its genetic material
Complex Viruses
Virus, They can be observed under the microscope
False, they cannot be observed under the microscope
Virus, They have internal cellular structure
False, they do not have internal cellular structure
