1

organisms too small to be seen without the unaided eye

Microorganisms

2

Rapidly growing cell, specifically pathogenic

Germs

3

Two things knowledge of microbes helps humans with

Prevent food spoilage. Prevent disease occurrence

4

Beneficial actions of microbes

Decompose organic waste, production of fermented foods (wine, cheese, bread), generate organic molecules and O2 by photosynthesis

5

How do microbes generate organic molecules and O2

Photosynthesis

6

Destructive actions of microbes include

Spoilage of food, disease causing, can be toxic

7

Who established the system of scientific nomenclature including rational naming of all organisms and binary nomenclature

Linnaeus

8

How many names does each organism have?

2

9

What are the 2 names of each organism

the genus and specific epihet

10

16

protozoa and algae are examples of

eukaryotes

17

Non cellular infective entities

viruses

18

Prokaryotes with a different cell wall and unique rRNA signatures that are frequent in extreme environments

Archaea

19

Unicellular prokaryotes, peptidoglycan cell walls

Bacteria

20

How is bacteria reproduced?

Binary fission

21

Mostly immobile, multicellular with diverse cell types, use organic chemicals for energy

Fungi

22

May be motile via pseudopods, cilia, or flagella. Unicellular eukaryotes, absorb or ingest organic chemicals

protozoa

23

Algae are what kind of organisms? Prokaryotes or eukaryotes?

eukaryotes

24

What is a eukaryote that uses photosynthesis for energy with cellulose cell walls and produce molecular oxygen and organic compounds? Aquatic habitats

Algae

25

What kind of organisms are multicellular animal parasites

Eukaryotes

26

Non living microbes that are acellular, consist of DNA or RNA core of hereditary material

Virus

27

Can replicate only when they are in a living host

Viruses

28

Core is surrounded by a protein coat

Viruses

29

1673

30

This person reported that living things were composed of little boxes or cells

Robert Hooke
