Question 1

General

Answer 1

Unicellular
Difference in cell wall
None seem to be pathogenic

Question 2

Crenarchaeota

Answer 2

Aquatic
Hyperthermophiles (113°C)
Some are acidophiles ( pH2-3)

Sulfolobus -70°-80°C , in anaerobic conditions oxidize sulfur
Thermoproteus - strict anaerobes, 85°C, flagella

Question 3

Euryarchaeota

Answer 3

Methanogens - CO2. to CH4 in presence of hydrogen
Halophiles- like high salt, photosynthesize with bacteriorhodopsin

Question 4

Rest

Answer 4

Korarchaeota - hydrothermal vents
Nanoarchaeota - symbiotic with other archaea
Thaumarchaeota - oxidize ammonia
