The endosymbiotic theory includes the idea that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by larger cells and developed a symbiotic relationship, leading to modern eukaryotic cells. It does not include the concept of gene flow between mitochondrial and nuclear genomes.

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.
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.
Endosymbiotic theory explains the formation of organelles surrounded by how many membranes?
Endosymbiotic theory explains the formation of organelles surrounded by two membranes. This theory suggests that eukaryotic organelles such as mitochondria and chloroplasts originated from symbiotic prokaryotic cells that were engulfed by a host cell, leading to a mutually beneficial relationship.
What are the 3 main steps of the endosymbiotic theory?
The three main steps of the endosymbiotic theory are: 1) the engulfment of a prokaryotic cell by a larger host cell, 2) the establishment of a symbiotic relationship between the two cells, and 3) the evolution of the endosymbiont into an organelle within the host cell.
The endosymbiotic theory has been developed to explain the emergence of?
The endosymbiotic theory has been developed to explain the emergence of eukaryotic cells, proposing that certain organelles within eukaryotic cells were once free-living prokaryotic organisms that were engulfed by a larger host cell and formed a symbiotic relationship. This theory is supported by evidence such as the mitochondria and chloroplasts having their own DNA and ribosomes, similar to bacteria.
Which of the following would not support the endosymbiotic theory of the origin of mitochondri and chloroplasts?
Both contain DNA
What is the theory that says prokaryotic parasites once lived in eukaryotic cells?
This is the endosymbiotic theory.
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 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.
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.
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.
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.
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.
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.
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 organisms created the modern mitochondria?
Aerobic bacteria evolved into mitochondria.It is explained in endosymbiotic theory.
Do mitochondria have a circular strand of DNA?
Yes, mitochondria have a small circular strand of DNA. This DNA encodes some of the genes necessary for the mitochondria to produce energy through a process called cellular respiration.
