Archaea Kingdom

Characteristics

• Prokaryotic

• Unicellular

• Cell wall composed of proteins

• Live in extreme environments

• Non-pathogenic

Three types

halophiles, acidophiles, thermophiles

Halophiles

High salty environments

Thermophiles

Highly warm environments

Acidophiles

Highly acidic environments

Differences between archaea and bacteria

• Archaea walls not made of peptidoglycan

• have different cell membrane structure

• methods of protein synthesis is different

• RNA molecules are different
