Plant cells only have one central (and large) vacuole. Prokaryotic- cells consisting of bacteria and blue-green algae, no true nucleus. Eukaryotic- cells consisting of all other organisms (the 4 remaining kingdoms (has a true nucleus) 2 domains that refer to cell type (first being prokaryotic organisms like blue- green algae, bacteria, and archaea, second domain being eukaryotes like protists, animals, fungi, plants) (fig.

Viruses force self into a cell to reproduce more viruses and spread. Can be considered most extreme form of a parasite. 3. 4 of book has diagram of prokaryotic cell. Bacteria has cell wall, dna, flagella tails on ends.
