fungi test Flashcards
know terms and not fail (26 cards)
what are the levels of classification
kingdom, phylum, class, order, family, genus, species
what are the different kingdoms
Protista, fungi, plantae, animalia
name a species from the protista kingdom
amoeba, seaweed, algea
name species from the fungi community
mushrooms, a common mold
name species from the Animalia kingdom
dog, tiger, koala, bass fish, robin
name species from the Plantae kingdom
venus flytrap, bamboo, pine tree
types of bacteria (shapes)
Spheres or ball-shaped (cocci bacteria).
Rod-shaped bacteria (bacilli).
Spirals or helixes (spirochetes).
how do bacteria reproduce
Conjugation: bacteria stick to each other via thier Pilli
Asexual reproduction: makes identical copies of itself
Binary fission
This increases the number of bacteria significantly.
bacteria versus viruses
bacteria are living cells
viruses are just protien with genetic infro
bacteria can reproduce sexual & asexualy
viruses ca only replicate via host cells
antibiodics can be used to kill bacteria
viruses can only be killed is te immune system can fight it
both can be helpful, bacteria helpos with food, ecysystem decomposing, viruses can be used in genetic treatment of some illnesses
lytic cycle
the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus.
lytic, Viruses attach to cell membrane
A virus penetrates the membrane and injects viral genetic information into the host
Viral genetic information destroys the host’s genetic information and begins to synthesize viral components
Viral components begin to assemble to make copies of the original virus
The virus kills the cell (cell lysis) by breaking pen the membrane and searching out new hosts
immunity
Activity immunity
Is when youre body has to actively make the antibodies in order to fight a disease
Passive immunity
Is when your body is given the antibodies and your body does not have to work for it
immune responses
fever, sore throat, coughing, sneezing, swelling of lymph nodes, tears
anything to flush out/destroy the virus
lysogeny
a viral reproductive stage where the virus’s DNA is replicated using the host cell’s DNA.
lysogeny
A virus attaches the members of the host
A virus penetrates the host membrane and injects viral genetic information into the cell
Viral genetic information leaves the cell nucleus and begins to destroy the cell making viral components and assembling the new virus
Each infected cell dies as the cells burst open to release the new viruses as they search for new hosts
fungi reproduction
the reproduce by releasing spores
The asexual cycle produces mitospores, and the sexual cycle produces meiospores
mitospores - asexual spores
meiospores - sexual spores
types of kingdom Protista
Plant-like protists
Animal-like protists
Fungi-like protists
Plant-like protists
describe protists
Most protists are microscopic unicellular aquatic organisms - tiny single cells aquatic organisms
Plant-like protists
Contain chlorophyll
Prokaryotic & Eukaryotic
Prokaryotic cell: a type of cell that does not have its chromosomes sourounded by a nuclear membrane
Eukaryotic cell: a type of cell that has a true nucleus the nuclear the membrane sourrounds a well-defined nucleus
importance of fungi
fungi and eubecta are decomposers so they help to decompose dead organisms ex. dead leaves
fungi are… (how do they eat)
heterotrophic - have to find thier food vs autotrophic make thier food
how do fungi eat (process)
fungi absorb thier nutrients via the thing they are attached to, their digestion is extracellular (outside of the cell)
where does the eating process take place
mycelia which are the branching filaments of the fungus
Mycelium
a branched mass of hyphae
Hyphae
thin filaments that make up the body of the fungus
Zygote (fungus)
a cell formed by the fusion of 2 nuclei
