Bacteria §Bacteria exist in two Kingdoms. §Archaebacteria l Live in extreme environments l Acids, intestines, sewage, 110 degree water etc l Produce foul odors §Eubacteria l Live everywhere else l Many are beneficial
Bacteria Reproduction §Asexual reproduction l Reproduction with only one parent l binary fission one cell divides to form two identical cells §Sexual Reproduction l Two parents combine genetic material l Conjugation Transfer genetic material through a thin bridge
Virus §Non-living l Do not use energy to grow l Do not respond to their surroundings l Sub-microscopic l Unable to grow or reproduce outside a host cell. A host is an organism that harbors a virus or parasite.
Virus §Each viral particle, or virion, consists of just two parts l Genetic material, DNA or RNA. l A protective protein coat called a capsid.
Virus §Viruses multiply by entering a host cell and taking over cell function with its own genetic material. §The infected host cells then produce more protein and genetic material to assemble new virion.
