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).

What is the autogenic hypothesis of the origin of the eukaryotic cell?
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.
How would the chief hypothesis concerning the origin of the ER and Golgi apparatus be described?
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.
Which two hypothesis were merged into what is know as the?
The two hypotheses that were merged to form the endosymbiotic theory are the autogenous hypothesis, which suggests that organelles evolved from prokaryotic cells that became internal structures in a eukaryotic cell, and the symbiotic hypothesis, which proposes that organelles originated from the mutualistic relationship between different types of cells. These two ideas were combined to explain the presence of organelles like mitochondria and chloroplasts in eukaryotic cells.
What is the likely origin of mitochondria?
Mitochondria likely originated from a symbiotic relationship between a primitive eukaryotic cell and an aerobic prokaryotic cell, possibly an ancestor of modern-day alphaproteobacteria. This symbiosis likely occurred through endosymbiosis, where the prokaryotic cell was engulfed by the eukaryotic cell but not digested, leading to a mutually beneficial relationship where the host cell provided a protected environment and the prokaryotic cell provided ATP through aerobic respiration.
What theory was developed around the idea that some eukaryotic organelles evolved from proyarotic organisms?
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.

What is the evolutionary hypothesis that some organelles are remnants of prokaryotic 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.
Which two hypothesis were merged into what is know as the?
The two hypotheses that were merged to form the endosymbiotic theory are the autogenous hypothesis, which suggests that organelles evolved from prokaryotic cells that became internal structures in a eukaryotic cell, and the symbiotic hypothesis, which proposes that organelles originated from the mutualistic relationship between different types of cells. These two ideas were combined to explain the presence of organelles like mitochondria and chloroplasts in eukaryotic cells.
What are the two theories of evolution in a eukaryotic cell?
The two theories of evolution in a eukaryotic cell are endosymbiotic theory and gene duplication. Endosymbiotic theory suggests that eukaryotic cells evolved from a symbiotic relationship between different prokaryotic organisms. Gene duplication theory suggests that gene duplication events have played a significant role in the evolutionary development of new functions and complexity in eukaryotic cells.
What is the ancestor of mitochondria?
One hypothesis is that mitochondria are "swallowed" bacteria that were not digested but instead incorporated into the cell as a symbiont (helper). Mitochondria have a membrane similar to the cell membrane and their own genetic material similar to bacteria.
What is the likely origin of mitochondria?
Mitochondria likely originated from a symbiotic relationship between a primitive eukaryotic cell and an aerobic prokaryotic cell, possibly an ancestor of modern-day alphaproteobacteria. This symbiosis likely occurred through endosymbiosis, where the prokaryotic cell was engulfed by the eukaryotic cell but not digested, leading to a mutually beneficial relationship where the host cell provided a protected environment and the prokaryotic cell provided ATP through aerobic respiration.
Is endosymbiotic theory true?
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.
What theory was developed around the idea that some eukaryotic organelles evolved from proyarotic organisms?
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.
What theory states that mitochondria and chloroplasts are derived from free-living prokaryotic cells?
The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by a primitive eukaryotic cell through symbiosis. Over time, these engulfed cells evolved into organelles within the host cell, leading to the development of modern eukaryotic cells.
What is biologists Lynn margulis's hypothesis about where the first protists came from?
Lynn Margulis proposed the endosymbiotic theory, suggesting that organelles such as mitochondria and chloroplasts in eukaryotic cells evolved from symbiotic relationships between different types of prokaryotic cells. This hypothesis explains the origins of protists and other eukaryotic organisms through the merging of different cell types rather than gradual evolution from a single organism.
What model is used to explain the origin of mitochondria and chloroplasts within eukaryotic cells?
I believe you are referring to the Endosymbiotic theoryby Lynn Margulis. She came up with the theory that states that eukaryotic cells engulfed smaller bacteria and over time, they became specialized organelles within eukaryotic cells.
