Question 1

Big shift in theory for Biologists

Answer 1

Realization that Prokaryotic organisms (Archaebacteria) had much in common with Eukaryotes as they did with true Bacteria and didn’t belong to either group. -Led to creation of new Taxonomic Category DOMAIN

Question 2

Domain

Answer 2

-Larger and more inclusive than Kingdoms -3 Domains: Archaea(archaebacteria) Bacteria(Eubacteria) Eukarya(Eukaryotics)

Question 3

Order of Groupings

Answer 3

Domain, Kingdom, Phylum, Class, Order, Family, Genus, species Don’t Kick Pussies Cunts Or Fucking Gorilla Sacks -Species not capitalized, Genus and Species underlined or capitalized

Question 4

What features or Archaea make them Prokaryotic?

Answer 4

Single celled organisms, No nucleus.

Question 5

3 Main groups of Archaea by Habitat?

Answer 5

METHANOGENS = Bogs, Sewage, intestinal tracts of ruminants HALOPHILES = High areas of salt, sea water THERMOPHILES = near hydrothermal vents, hot springs

Question 6

Bacteria

Answer 6

Peptidoglycan in cell wall One kind of RNA Polymerase

Question 7

Archaea

Answer 7

-

Question 8

Eukarya

Answer 8

-

Question 9

Bacteria Morphololgy

Answer 9

-“traditional bacteria” first observed by -Leeuwenhoek 300 Years ago. -Basic, but universal way to classify bacterial diversity of small non-photosynthetic cells

Question 10

Types of bacteria Morphology

Answer 10

COCCI (Coccus singular) = Round Bacteria BACILLI (Bacillus singular) = Rod Shaped SPIRILLA (Spirillum singular) = Long, Spirally coiled

Question 11

Cyanobacteria Origins

Answer 11

50 years ago transmission electron microscope was able to uncover blue algae thought to be eukaryotic were actually prokaryotic = Cyanobacteria

Question 12

Cyanobacteria Characteristics

Answer 12

-Much Larger than “traditional bacteria” -Grow in multicellular filaments -Photosynthetic

Question 13

Coccus

Answer 13

Question 14

Bacillus

Answer 14

Question 15

Spirillum
