Comparing Bacteria and Archaea

Question 1

Prokaryotes fall under 2 of the 3 domains….

Answer 1

Bacteria and Archaea

Question 2

Bacteria and Archaea can be classified on which 3 shapes

Answer 2

cocci (round), bacilli (rods), and spirillum (spiral)

Question 3

Aggregations

Answer 3

clusters of cells grouped together

Question 4

Nutrition for Bacteria and Archaea

Answer 4

Methanogenesis (A) and Photosynthesis (B)

Question 5

Methanogenesis

Answer 5

Unique to Archaea, biological process used to create energy: uses methane as a byproduct

Question 6

Photosynthesis (bacteria)

Answer 6

Unique to bacteria, uses sunlight to create energy “cyanobacteria”

Question 7

Habitat of Bacteria and Archaea

Answer 7

can exist in aerobic and anaerobic environments
B: Mesophiles - moderate conditions
A: Extremophiles - extreme conditions

Question 8

What are some of the extreme conditions archaea can live in

Answer 8

Thermophile - heat lover
Halophile - salt lover
Acidophile - acid lover

Question 9

What is binary fission

Answer 9

It happens in both bacteria and archaea, its when the cells replicate by the cytoplasm splitting at the septum creating 2 indentical daughter cells

Question 10

What are 2 things that happen when bacteria is living in less favourable conditions

Answer 10

Conjugation and Creation of endospores

Question 11

Conjugation

Answer 11

When bacteria passes on genetic material from cell to another

Question 12

Creation of endospores

Answer 12

It has structures that store genetic material that is resistant to extreme environments. They cannot like as an endospore forever only temporary.
