Autogenic means produced from within, or self-generating. Therefore the 'autogenic hypothesis' is most likely to be that the organelles and structures of a Eukaryotic cell were self-generated by a Prokaryotic cell - and this is how Eukaryotic cells were created.
The theory of Endosymbiosis is much more widely accepted.
The chief hypothesis concerning the origin of the endoplasmic reticulum (ER) and Golgi apparatus is the endosymbiotic theory. This theory suggests that these organelles originated from the engulfment of prokaryotic cells by ancestral eukaryotic cells, forming a symbiotic relationship where the engulfed cells evolved into organelles within the host cell. This process eventually led to the development of these complex membrane-bound organelles in eukaryotic cells.
The endosymbiont hypothesis suggests that eukaryotic cells evolved from a symbiotic relationship between different types of prokaryotic cells. This hypothesis explains the presence of organelles such as mitochondria and chloroplasts in eukaryotic cells, which are thought to have originated from ancient prokaryotic cells that were engulfed by a host cell but not digested.
A fat cell is a eukaryotic cell. All of the cells in a eukaryotic organism are eukaryotic.
A sperm cell is eukaryotic.
The theory is that the original Eukaryotic cell came about by the consumption of a Prokaryotic cell by another Prokayotic cell. This smaller cell was incorporated into the processes of the other - thus forming a symbiosis. This theory is supported by the fact that chloroplasts and mitochondria have their own DNA (separate from the nucleus).
The endosymbiotic hypothesis posits that eukaryotic cells originated through symbiotic relationships between different species of prokaryotes, which explains the presence of mitochondria and chloroplasts with their own DNA. Its strength lies in the genetic and structural similarities between these organelles and prokaryotes, providing strong evolutionary support. However, it may struggle to explain the full complexity of eukaryotic cell structures and functions. In contrast, the autogenic hypothesis suggests that eukaryotic cells evolved from prokaryotic ancestors through internal compartmentalization, emphasizing the role of cellular mechanisms. While it accounts for cellular complexity, it lacks the compelling evolutionary evidence seen in the endosymbiotic model.

According to one hypothesis, once there was the ancestor of a eukaryotic cell, which swallowed a bacterium. But instead of digesting it, the eukaryotic cell used the bacterium to yield energy by feeding it. In other words, a symbiosis formed, where the former bacterium is protected from foes and gets sugar, whereas the eukaryote gets ATP.This hypothesis is based on the facts ofthe double cell wall of the mitochondria (the inner one rough like a bacterium one, the outer smooth like from a lysosome)the own DNA of the mitochondriathe 70S ribosomes (like bacteria have it) instead of eukaryotic 80S ribosomes
