Virus Must Haves: Viruses require a host to replicate Extracellular state Intracellular state Viral life cycle: Attachment Entry Replication Assembly May Haves: Beneficial or pathogenic DNA or RNA Single or double stranded Animal, plant, or bacteriophage Rod-shape or spherical
3
Virus Influenza VirusViral Structure (DNA or RINA)
4
Bacteria Must Haves: Unicellular Prokaryotes Smallest living organisms .1-10um High surface area to mass ratio Binary Fission May Haves: Pathogenic and beneficial Response to oxygen Aerobic Anaerobic Facultative anaerobes Energy consumption/production Heterotrophic Autotrophic Taxonomy Eubacteria Archaebacteria
