Endosymbiotic Theory
concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

The endosymbiotic theory proposes that some organelles, such as mitochondria and chloroplasts, were once free-living prokaryotic cells that were engulfed by a host cell through endocytosis. Over time, these prokaryotic cells formed a symbiotic relationship with the host cell, eventually evolving into permanent organelles within the eukaryotic cell.
The endosymbiotic theory proposes that organelles such as mitochondria and chloroplasts in eukaryotic cells were once independent prokaryotic organisms that were engulfed by a host cell. Over time, these organelles formed a symbiotic relationship with the host cell, eventually becoming integrated as essential components of eukaryotic cells. This theory is supported by evidence such as the presence of DNA and ribosomes in these organelles, similar to prokaryotic cells.
The endosymbiont theory is associated with mitochondria and chloroplasts. It proposes that these organelles originated from primitive prokaryotic cells that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
Prokaryotes are much simpler organisms than eukaryotes. It is thought that eukaryotes evolved from prokaryotes. In both cases the evolution process was lengthy and similar to the evolution of other organisms.
Mitochondria and chloroplasts have prokaryote-like features. For example, although most of the DNA in eukaryotic cells resides in the nucleus, both mitochondria and chloroplasts have DNA molecules in their inner compartments. Mitochondrial and chloroplastic ribosomes are similar to the ribosomes of prokaryotes. The endosymbiont theory proposes that eukaryotic organisms evolved from prokaryotic ancestors; this idea supports the notion that organelles evolved from prokaryotic organisms that originally lived inside larger cells, eventually losing the ability to function as autonomous organisms
The endosymbiosis theory proposes that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms. It suggests that organelles such as mitochondria and chloroplasts were once independent prokaryotes that were engulfed by a host cell, eventually forming a mutually beneficial relationship.
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 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.

The endosymbiotic theory proposes that eukaryotic organelles, such as mitochondria and chloroplasts, originated from engulfed prokaryotic cells that developed a symbiotic relationship within the host cell. This theory suggests that these organelles were once free-living bacteria that were engulfed by early eukaryotic cells and eventually evolved into essential components of eukaryotic cells.

Yes, the endosymbiotic theory is widely accepted as a valid explanation for the origin of eukaryotic cells. It proposes that mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by a larger host cell, forming a symbiotic relationship. Over time, these engulfed organisms evolved into organelles within the host cell.
The endosymbiotic theory is a scientific hypothesis that proposes that eukaryotic cells evolved from symbiotic relationships between different types of prokaryotic cells. Specifically, it suggests that organelles like mitochondria and chloroplasts were once independent prokaryotic organisms that were engulfed by larger cells and developed a mutually beneficial relationship. This theory is supported by evidence such as the similarities between organelles and certain types of bacteria.
