The endosymbiotic theory is widely accepted as a strong scientific hypothesis; however, definitive proof is challenging due to the lack of direct observational evidence from billions of years ago when the theorized events occurred. While there is substantial supporting evidence, such as the similarities between organelles like mitochondria and chloroplasts with free-living bacteria, the theory cannot be definitively proven beyond any doubt.

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 statement fails to support the endosymbiotic theory?
A statement that fails to support the endosymbiotic theory would be one that asserts that all eukaryotic organelles were independently formed within the cells, without any symbiotic relationship with prokaryotic cells. This contradicts the evidence and principles of the endosymbiotic theory, which suggests that organelles like mitochondria and chloroplasts originated from ancient symbiotic relationships between prokaryotic cells and ancestral eukaryotic cells.
The endosymbiotic theory provides the explanation for the origin of what?
The endosymbiotic theory explains the origin of eukaryotic cells by proposing that mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by primitive eukaryotic cells. Over time, a symbiotic relationship developed, leading to the integration of these organelles into eukaryotic cells.
Which discovery supported the endosymbiotic theory?
The discovery of mitochondria and chloroplasts having their own DNA, ribosomes, and double membrane structure supports the endosymbiotic theory, which proposes that these organelles were once free-living prokaryotes that were engulfed by ancestral eukaryotic cells. This evidence suggests that they evolved from symbiotic relationships between different cell types.
Why do people consider the cell theory a theory?
Because a theory is not completely proved yet and it could not be completely proven yet or it was called that before they proved it and they just kept the same name so people knew what they were talking about!!!!! :)
What describes a scientific theory?
something that is used to describe something, but isn't proved yet
What is the theory that says prokaryotic parasites once lived in eukaryotic cells?
This is the endosymbiotic theory.
What is the endosymbiotic theory?
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.
The endosymbiotic theory was supported by the scientist?
Lynn Margulis was the scientist who proposed and championed the endosymbiotic theory. She provided evidence to support the idea that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms.
Theory of endosymbiosis?
The endosymbiotic theory explains the origin of chloropasts and mitochondia. Symbiosis is the mutual benefit of two organisms living together. This was the basis of the theory.
When was the endosymbiotic theory proposed?
The endosymbiotic theory was proposed in the 1960s by Lynn Margulis to explain the origin of eukaryotic cells. It suggests that eukaryotic cells evolved through a mutually beneficial relationship between primitive prokaryotic cells.
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.
How is a theory different from a hypothesis?
A hypothesis is a guess in what you think it is a theory is a fact and someone already proved it in the past.
Which of the following would not support the endosymbiotic theory of the origin of mitochondri and chloroplasts?
Both contain DNA
What organisms created the modern mitochondria?
Aerobic bacteria evolved into mitochondria.It is explained in endosymbiotic theory.
Who proved the world is flat theory wrong?
Eratosthenes proved the world is flat theory wrong
