The endosymbiotic theory suggests that eukaryotic cells arose from a mutual relationship of prokaryotic cells. Evidence shows that prokaryotic and eukaryotic cells share many characteristics. The theory focuses on the origins of the chloroplasts and mitochondria of photosynthetic prokaryotes and aerobic heterotrophs, respectively.
The similarities in characteristics include:
1. They both go through binary fission to reproduce
2. Eukaryotes are about the same size as eubacteria
3. The ribosomes of the eukaryotes, when examined with great detail, more resemble those of a prokaryote than a eukaryote
Scientists believe that archezoa, a eurkaryotic organism, most resembles the prokaryotes. It does not contain mitochondria.
What else can I help you with?
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.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
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.
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.
Which of the following would not support the endosymbiotic theory of the origin of mitochondri and chloroplasts?
Both contain DNA
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.
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.
