Answer 2

rRNA

Question 3

……….. is a population of microbial cells growing in the absence of other species or types

Answer 3

Pure Culture

Question 4

…………. is the genetic material of all the microbes - bacteria, fungi, Protozoa and viruses- that live on and inside the human body

Answer 4

Microbiome

Question 5

…………. are “ecological communities of Commensal, symbiotic, and pathogenic microorganisms” that literally share our body space.

Answer 5

Microbiota

Question 6

Difference between Anaerobic and Aerobic Bacteria?

Answer 6

Anaerobic are single called organisms that don’t need oxygen to survive, Aerobic are bacteria that can grow and survive when it is oxygen

Question 7

The …….. is the genetic makeup of a cell, an organism, or an individual usually with reference to a specific characteristic under consideration

Answer 7

Genotype

Question 8

How do we get our microbiome?

Answer 8

During the birth, breast feeding, environment

Question 9

Which types of microorganism has organism as Bacteria and Archaea?

Answer 9

Prokaryotic Organisms

Question 10

Which types of microorganism has organism as Fungi, Protozoa and Algea?

Answer 10

Eukaryotic microorganisms

Question 11

……….(single type of cells) Mostly live in communities and arranged in pairs, chains, clusters or other groupings

Answer 11

Unicellular

Question 12

……………. is a polymer consisting of sugar and amino acids that forms a mesh like layer outside the plasma membrane of most bacteria that forms the cell wall.

Answer 12

Peptidoglycan cell wall

Question 13

“………..” are small single celled organisms, they are 10 times as many “………….” cell as human cells in the human body

Answer 13

Bacteria

Question 14

How do bacteria RePRODUCE?

Answer 14

Bacteria reproduce by “binary fission. “ . in this process the bacterium divides into two identical daughter cells. “.binary fission” begins when the DNA of the bacterium splits into two replicates. The bacteria cell than elongates and splits into two daughter cells each with identical DNA as their parent cell.

Question 15

Single-celled prokaryotic organism, they are “Extremophiles” that means they are adapted to extreme environments( very hot, cold, saline, acidic) which bacteria is that?

Answer 15

Archaea

Question 16

Singular cells have also nucleus. 3 mayor groups: YEASTS, FUNGI AND MUSHROOMS. are multicellular except for YEAST. Their cell walls are CHITIN, that is a composed of filaments

Answer 16

Fungi eukaryotic microorganisms

Question 17

Unicellular eukaryotes, they are diverse group, may be motile via pseudopods, cilia or flagella.

Answer 17

Protozoa eukaryotic microorganism’s

Question 18

May be unicellular or multicellular, the cell was is made of Cellulose. It is found in freshwater, saltwater. It uses photosynthesis for energy. It also produces oxygen and carbohydrates

Answer 18

.Algae eukaryotes cell

Question 19

Its acellular, consist of DNA and RNA core, and the core is surrounded by a protein coat. Protein coat may be enclosed with in a lipid envelope. They only replicate when they are living in a host cell.

Answer 19

Virus

Question 20

They are Eukaryotes and is find in multicellular animals, not strictly a microorganism.

Answer 20

Multicellular animal Parasites.

Question 21

Bacteria is classified into five groups according to their basic shapes:

Answer 21

Spherical (cocci), Rod (bacilli), spiral ( spirilla), comma (vibrios) or corkscrew (spirochaetes)
