Detailed explanation-1: -The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes-endosymbiosis-is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Detailed explanation-2: -The endosymbiotic theory is the accepted mechanism for how eukaryotic cells evolved from prokaryotic cells. It involves a cooperative relationship between two cells which allow both to survive-and eventually led to the development of all life on Earth.

Detailed explanation-3: -Abiogenesis is a scientific theory which states that life arose on Earth via spontaneous natural means due to conditions present at the time. In other words, life came from non-living matter.

Detailed explanation-4: -The endosymbiotic theory explains how eukaryotic cells evolved. The large and small cells formed a symbiotic relationship in which both cells benefited. Some of the small cells were able to break down the large cell’s waste s for energy. They supplied energy not only to themselves but also to the large cell.
