Q

What do you call a circular bacteria that is in pairs and is located on the end of the cell?

A

Diplococci/Diplococcus

24
Q

What do you call a curved or twisted bacteria that is very common with sea creatures like the cuttlefish?

A

Vibrios

25
Q

This cell do not have true nucleus and lacks membrane enclosed-organelles.

A

Prokaryotes

26
Q

Why is it important for the salt farm to be color red?

A

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.

27
Q

What do you call microorganisms that can thrive in lower temperature and also can live in normal condition?

A

Psychrophile

28
Q

This species is an example of bacteria that is glowing and lives in the body of cuttlefish.

A

Aliivibrio

29
Q

What do you call a bacteria that is elongated?

A

Bacilli/Bacillus or Rods

30
Q

What do you call a circular bacteria that is large and is in an irregular cluster?

A

Micrococci or Staphylococci/Staphylococcus

31
Q

These microorganisms are photosynthetic eukaryotes that have an important role in balancing the enviroment.

A

Algae

32
Q

What happens in the asexual life cycle of fungi?

A

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

33
Q

Why is the Deinococcus radiodurans being explored?

A

Because of the possibility that we can use this to revive waste lands that are affected by radiation

34
Q

What is the study of naming, describing, and classifying organisms?

A

Taxonomy

35
Q

What do you call microorganisms that are acid loving?

A

Acidophiles

36
Q

What do you call the bacteria that is elongated, filamentous, and that causes petrichor scent?

A

Streptomycetes

37
Q

What do you call the circular bacteria that are in packets of 8, 16, or 32 cells?

A

Sarcinae

38
Q

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.

A

Lactobacillus

39
Q

What is the cell that has a nucleus, membrane enclosed-organelles, linear DNA, and is multicellular?

A

Eukaryotes

40
Q

What do you call microorganisms that live on high salt concentration areas?

A

Halophiles

41
Q

What do you call a group of organisms classified as a unit?

A

Taxon or Taxa

42
Q

What do you call a curved or twisted bacteria that moves like a screw?

A

Sprilla and Spriochetes

43
Q

Why is it important to know the arrangement of bacteria?

A

Because it is used for identifying them

44
Q

What do you call an elongated bacteria that is shorter than normal bacillus but longer than cocci?

A

Coccobasillus/Coccobasilli

45
Q

What do you call a circular bacteria that is in the shape of coffee bean but its pairing is more on lateral?

A

Neisseriae

46
Q

What do you call a bacteria that is very elongated like a filament?

A

Mycobacteria

47
Q

Explain how do petrichor scent happens.

A

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.

48
Q

What elongated bacteria has endospore, that looks like a nail under the microscope?

A

Spore-forming rod

49
Q

What domain of life is single-celled and multi-celled organisms with true nucleus and membrane bound organelles?

A

Eukarya

50
Q

How do you distinguish bacteria?

A

Gram-negative bacteria and gram-positive bacteria

51
Q

What do you call a circular bacteria that is formed in chain and is a very common found in the skin?

A

Streptococci/Streptococcus

52
Q

What is the process of naming or designing names to organisms?

A

Nomenclature

53
Q

This is a elongated bacteria that is palisade in arrangement and shape such as the end is larger than the other.

A

Corrynebacteria

54
Q

What do you call a circular bacteria that is packed in packets of 4?

A

Tetrad

55
Q

What microorganism lives on the green area on a salt farm?

A

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.
