There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea and are small and lack organelles and a nucleus. Eukaryotic cells include unicellular protists and multicellular fungi, plants and animals, and are larger and have membrane-bound organelles and a nucleus. The document provides examples of characteristics of prokaryotic and eukaryotic cells.
