12 Bacteria Reproduction Asexual reproductionReproduction with only one parentbinary fissionone cell divides to form two identical cellsSexual ReproductionTwo parents combine genetic materialConjugationTransfer genetic material through a thin bridge
17 Virus Non-living Do not use energy to grow Do not respond to their surroundingsSub-microscopicUnable to grow or reproduce outside a host cell.A host is an organism that harbors a virus or parasite.
18 Virus Each viral particle, or virion, consists of just two parts Genetic material, DNA or RNA.A protective protein coat called a capsid.
19 VirusViruses 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.
