Module 1 Lesson 1

Question 1

Translates to “the study of small life,” where the small life refers to microorganisms or microbes.

Answer 1

Microbiology

Question 2

are microscopic organisms that exist as cellular
microbes (or organisms) and the acellular microbes (or agents).

Answer 2

Microorganisms or microbes

Question 3

where one cell is the entire organism

Answer 3

unicellular

Question 4

Where numerous number of cells can make up the entire organism

Answer 4

multicellular

can infect and cause diseases on human, plants or animals

Answer 5

Pathogenic microorganism

Question 6

are beneficial to the host.

Answer 6

nonpathogenic microorganisms

Question 7

Is a population of microorganisms naturally present within a healthy body. It could be on the skin surface, within natural body cavities, in the gastrointestinal tract or reproductive tract.

Answer 7

normal Flora

Question 8

Answer 11

Metabolic characteristics

Question 12

: distinctive chemical components (antigens) of the microorganism

Answer 12

Antigenic characteristics

Question 13

Hereditary material of the cell

Answer 13

Genetic characteristics

Ability to cause disease of microorganisms

Answer 14

Pathogenicity

Question 15

Habitat and distribution of microorganisms in nature, and interaction between and among species in natural environment

Answer 15

Ecological characteristics

prokaryotes (no nuclear membrane); unicellular; enclosed in cell
walls rich in carbohydrates and peptidoglycan; divides by binary fission.

Answer 16

Bacteria

Question 17

Question 19

unicellular eukaryotic; move by appendages.

Answer 19

Protozoa

Question 20

photosynthetic eukaryotes; cell walls are made of cellulose (plant
carbohydrate).

Answer 20

Algae

Question 21

Acellular microorganism; made either of DNA or RNA surrounded by a protein
coat, that is sometimes further encased in a lipid membrane; need host cells to
reproduce.

Answer 21

Virus

Question 22

although not strictly microorganisms, these organisms
are microscopic in some stages of their development. Also use microbiological
techniques in their diagnosis.

Answer 22

Multicellular animal parasites
