Theory of Endosymbiosis - Eukaryotic cells emerged when mitochondria and chloroplasts, once free-living prokaryotes, took up permanent residence inside other larger cells, about 1.5 billion years ago. Eukaryotic Cell - A type of cell with a membrane-enclosed nucleus and membraneenclosed organelles. Organisms with eukaryotic cells (protists, plants, fungi, and animals) are called eukaryotes. Prokaryotic Cell - A type of cell lacking a membrane-enclosed nucleus and membraneenclosed organ...
