The organelles associated with the endosymbiont theory are mitochondria and chloroplasts. This theory posits that these organelles originated from free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells. Evidence supporting this includes their own circular DNA, double membranes, and similarities to bacteria. This symbiotic relationship is believed to have been beneficial, leading to the evolution of complex eukaryotic cells.
What else can I help you with?
What is endosymbiont theory?
An endosymbiont or endobiont is any organism that lives within the body or cells of another organism, i.e. forming an endosymbiosis
How are mitochondria and chloroplasts manufactured in the cell?
Both of them are thought to have originated from primitive bacteria. This theory is called Endosymbiont theory.
What organelles are associated with ednosymbiont theory?
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.
What was the theory developed around the idea some eukaryotic organelles evolved from prokaryotic organisms?
endosymbiont
After ln margulis's endosymbiont theory met oppositon what new evidnece emerged in support of the theory?
main distinction between euayotes and prokaryotes
Where Might have Mitochondria originated from?
From early prokaryotes that lived symbiotically with eukaryotic cells Margules endosymbiont theory
What theory was developed around the idea that some eukaryote organelles evolved from prokaryotics organisms?
endosymbiont
Tue or false the endosymbiont theory suggests that eukaryotes evolved through a symbiotic relationship between prokaryotes?
true
What is the endosymbiont theory?
The endosymbiont theory posits that certain organelles in eukaryotic cells, specifically mitochondria and chloroplasts, originated from free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells. This symbiotic relationship allowed the host cell to benefit from the energy-producing capabilities of these prokaryotes. Evidence supporting this theory includes the fact that mitochondria and chloroplasts have their own DNA, which is similar to bacterial DNA, and they replicate independently of the cell. Thus, the theory explains the evolutionary origin of complex cells.
The clinker theory is associated with?
clinker theory is associated with growth
What implication does the endosymbiont theory have for phylogeny?
The endosymbiont theory proposes that organelles like mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by a host cell and developed a symbiotic relationship. This has implications for phylogeny as it suggests that certain organelles have a different evolutionary history than the rest of the cell, leading to the concept of lateral gene transfer and complicating the interpretation of evolutionary relationships based on traditional phylogenetic methods.
What role does the endosymbiont theory play in explaining the origin of eukaryotic cells?
The endosymbiont theory explains that eukaryotic cells evolved from a symbiotic relationship between different types of prokaryotic cells. This theory suggests that mitochondria and chloroplasts, which are organelles in eukaryotic cells, were once independent prokaryotic cells that were engulfed by a larger host cell. Over time, these prokaryotic cells became integrated into the host cell and eventually evolved into the organelles we see in eukaryotic cells today. This theory helps to explain the presence of these organelles in eukaryotic cells and provides insight into the evolutionary history of these complex cells.
