Did eukaryotic cells come from bacteria
Eukaryotes evolved during the Proterozoic eon approximately 1.6 BYA. Prior to the origin of eukaryotes, all life on Earth was prokaryotic (lacking nucleus or other membrane-bound organelles).

Symbiosis is the interaction between two different organisms living in close physical association, typically to the advantage of both. Endosymbiosis is symbiosis in which one of the symbiotic organisms lives inside the other. Hence the use of the prefix "endo".

WebMar 28, 2024 · Eukaryotic cells probably evolved from bacteria, and started out as hunters. They scooted around engulfing other, smaller cells. But some of those smaller cells didn’t get digested after they were eaten. Instead, they stuck around inside their larger host. These smaller cells now perform essential functions in eukaryotic cells. WebProkaryotes recycle nutrients —essential substances (such as carbon and nitrogen)—and they drive the evolution of new ecosystems, some of which are natural and others man-made. Prokaryotes have been on Earth since long before multicellular life appeared. Indeed, eukaryotic cells are thought to be the descendants of ancient prokaryotic ...
