Microbial Diversity and Taxonomy Flashcards
Enumerate the 3 main domain of life
Archaea, Bacteria, Eukarya
What are the similarities of Prokaryotes and Eukaryotes?
Both are unicellular and have cell but not all
What domain of life has single-celled microorganisms, lacks true nucleus and membrane-bound organelles, and has a cell wall called peptidoglycan?
Bacteria
Enumerate the 3 major arrangement of Bacteria?
Coccus/Cocci, Bacillus/Bacilli or Rod, Spirillum/Spirochete
This is an example of a microorganism under Eukarya that can be single-celled or very complex multicellular organisms and are found in just about any habitat, mostly on the land.
Fungi
What is the process of assigning of organisms to their respective taxon or taxa?
Classification
__________ is one of streptomycetes and causes the petrichor scent.
Actinomyces species
What is the microorganism that live near volcanic vents or hydrothermal vents under the ocean that has an optimum temperature for growth greater than 80 degrees Celsius?
Hyperthermophiles
Why is the salt farm color red?
This is caused by halophiles that live there, microorganism that has pigments.
Enumerate 3 examples of species under the domain Archaea.
Sulfulobolus, Haloferox, Methanopyrus
This is one of the example of species under the domain Bacteria that causes acne.
Cutibacterium Species
What do you call a bacteria that is curved or twisted?
Spirillum/Spirochete
It is the range of different taxon or taxa.
Diversity
What happens in the sexual life cycle of fungi?
It is the life cycle of fungi that creates mushroom or fruiting body
What domain of life is morphologically identical to bacteria and does not have peptidoglycan?
Archaea
What do you call microorganisms that can survive normal conditions?
Mesophilic
What do you call a bacteria that are circular or spherical?
Cocci/Coccus
This is an example of a bacteria that has a potential of deterring or can still live in radioactive condition.
Deinococcus radioduran
A microorganism under Eukarya that live in a wide variety of moist habitats. Some are parasitic.
Protozoa
What is the process of recognition of identity or essential character of an organism?
Identification
What do you call the pigments of halophiles?
Rhodopsin and Ruberin
“Most species are extremophiles.” This is a common misconception of which domain of life.
Archaea
What do you call a circular bacteria that is in pairs and is located on the end of the cell?
Diplococci/Diplococcus
What do you call a curved or twisted bacteria that is very common with sea creatures like the cuttlefish?
Vibrios
This cell do not have true nucleus and lacks membrane enclosed-organelles.
Prokaryotes
Why is it important for the salt farm to be color red?
When the water turns red, it kind of absorb more heat from the sun. If the water is redder, the quicker for the water to be heated. If the water is heated, the quicker it is to be evaporated. That means the salt will be crystalized quicker and it will be harvest quicker.
What do you call microorganisms that can thrive in lower temperature and also can live in normal condition?
Psychrophile
This species is an example of bacteria that is glowing and lives in the body of cuttlefish.
Aliivibrio
What do you call a bacteria that is elongated?
Bacilli/Bacillus or Rods
What do you call a circular bacteria that is large and is in an irregular cluster?
Micrococci or Staphylococci/Staphylococcus
These microorganisms are photosynthetic eukaryotes that have an important role in balancing the enviroment.
Algae
What happens in the asexual life cycle of fungi?
This cycle creates vegetative form or mycelial. It only happens when there is a shortage of food and when that happens, the fungi creates a fruiting body. This cycle happens in order to easily spread spores and for it to transfer to different environment that has food
Why is the Deinococcus radiodurans being explored?
Because of the possibility that we can use this to revive waste lands that are affected by radiation
What is the study of naming, describing, and classifying organisms?
Taxonomy
What do you call microorganisms that are acid loving?
Acidophiles
What do you call the bacteria that is elongated, filamentous, and that causes petrichor scent?
Streptomycetes
What do you call the circular bacteria that are in packets of 8, 16, or 32 cells?
Sarcinae
This species is an example of bacillus bacteria that is very common in the food industry. It is found on yogurt and probiotic drinks like Yakult and Delight.
Lactobacillus
What is the cell that has a nucleus, membrane enclosed-organelles, linear DNA, and is multicellular?
Eukaryotes
What do you call microorganisms that live on high salt concentration areas?
Halophiles
What do you call a group of organisms classified as a unit?
Taxon or Taxa
What do you call a curved or twisted bacteria that moves like a screw?
Sprilla and Spriochetes
Why is it important to know the arrangement of bacteria?
Because it is used for identifying them
What do you call an elongated bacteria that is shorter than normal bacillus but longer than cocci?
Coccobasillus/Coccobasilli
What do you call a circular bacteria that is in the shape of coffee bean but its pairing is more on lateral?
Neisseriae
What do you call a bacteria that is very elongated like a filament?
Mycobacteria
Explain how do petrichor scent happens.
When it rains and the actinomyces get wet by it, its spores splatter in the air along with the geosmin compound. This compound is the one causing the scent.
What elongated bacteria has endospore, that looks like a nail under the microscope?
Spore-forming rod
What domain of life is single-celled and multi-celled organisms with true nucleus and membrane bound organelles?
Eukarya
How do you distinguish bacteria?
Gram-negative bacteria and gram-positive bacteria
What do you call a circular bacteria that is formed in chain and is a very common found in the skin?
Streptococci/Streptococcus
What is the process of naming or designing names to organisms?
Nomenclature
This is a elongated bacteria that is palisade in arrangement and shape such as the end is larger than the other.
Corrynebacteria
What do you call a circular bacteria that is packed in packets of 4?
Tetrad
What microorganism lives on the green area on a salt farm?
Algae, probably Dunalielia. With higher salt concentration, it can reach the optimum temperature and optimum salt concentration. This turns the green area to a red one, meaning the green algae turns red.
