Eukaryotes are generally more advanced than prokaryotes. There are many unicellular
organisms which are eukaryotic, but all cells in multicellular organisms are
It is hypothesized that a primitive bacterium once surrounded its food after releasing its digestive enzymes. The membrane folded inward and pinched off, creating the first digestive membrane-bound organelle.
Once upon a time (about one billion years ago), the first eukaryotic cell came to be. There was a group of primitive bacteria going about their business when along came a big hungry phagocyte, who ate one of the bacterium.
Mr. Phagocyte: Yum.
The little engulfed bacterium evolved and became the mitochondria in present-day cells.
