Prokaryotes and eukaryotes review - Khan Academy
This theory proposes that organelles like mitochondria and chloroplasts were once free-living prokaryotic cells that began to live within a larger host cell. Over a long time, the prokaryotes and their hosts evolved together until one could not function without the other.
Prokaryotic and eukaryotic cells (video) | Khan Academy
Eukaryotic cells are generally larger and more complex than prokaryotic cells. Eukaryotic organisms include animals, plants, fungi, and paramecia. Prokaryotic organisms include bacteria and archaea.
Formatting Tips - Khan Academy
It's a traditional eukaryotic cell, but what I want to do is see what happens when a phagocyte encounters a foreign particle or a foreign bacteria. So let me say this is a foreign bacteria right here.
