What kind of cells can viruses infect? ~~> viruses infect every type of cell, including bacteria, algae, fungi, protozoa, plant, and animals Are viruses alive? ~~> two sides of the debate: 1. since viruses are unable to replicate independently from the host cell, so no, not alive 2. even though viruses do not exhibit most of the life processes of cells, they can direct them, so more than inert (lacking strength/ability to move) and lifeless molecules viruses are better desc...
