- no membrane bound nucleus or organelles
- generally smaller than eukaryotes
- simple internal structure
- divide by binary fission
- most are unicellular
5
Q
2 major groups of prokaryotes
A
- bacteria
- archaea
6
Q
bacteria
A
(eubacteria)
- genetically diverse
- extremely diverse metabolic styles
- includes both pathogens and non-pathogens
- live in a broad range of ecosystems
7
Q
archaea
A
(archaebacteria)
- genetically and biochemically distinct from bacteria
- also have diverse metabolism
- never pathogenic
- most famous for living in extreme environments
8
Q
viruses
A
- acellular infectious particles
- extremely small
- obligate intracellular parasites
- lack independent metabolism
- no ribosomes
- no ribosomal RNA
- cannot be classified with other microbes
9

membrane bound nucleus
membrane bound organelles
complex internal organization
division by mitosis and meiosis
