Core Concepts Prokaryotes are classified into two domains/kingdoms: Bacteria and Archaea Presence of peptidogycan in bacteria Some archaea have pseudopeptidoglycan Diverse cell wall, some made up of proteins called S layer
Bacteria are identified by their shapes, the chemical natures of their cell walls, the ways they move and the ways they obtain and use energy Bacteria reproduce asexually by binary fission. Through the process of conjugation, genes can move from one cell to another, thus increasing genetic diversity within bacterial populations
Prokaryotes play a crucial role in the biosphere, such as taking part in nutrient cycles and in symbiotic relationships. Also, they have both harmful and beneficial impacts on humans
