Avoid the crisis' of viruses!!
Madison Green & Christina Chung
What they do to cells: infect cellsand cause dieases in animals, plants, and bacteria, use cells to make more viruses, and change over time (mutate)
How they reproduce: viruses attach to host cells, viruses inject DNA or RNA into cell, virus' genetics material take over cell, host cell makes virus parts, virus parts assemble in cell
Size: Viruses: 20-250 nano-grams Bacteria: about 1,000 nano-grams Animal Cell: 10,000-100,000 nano-grams
Why they are not cells: not made of cells, cannot produce on their own, cannot move, do not go through cellular respiration (do not make ATP), and do not eat
