What is the endosymbiotic theory What is the evidence for it?
Explanation: Bacteria, a prokaryote, has circular DNA, as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory, which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).
What evidence do scientists observe today that supports the theory of endosymbiosis?
Single stranded, circular DNA is found exclusively in prokaryotes. This evidence supports the endosymbiosis theory because these characteristics would allow the mitochondria and chloroplasts to survive on their own.
What is evidence for the endosymbiotic theory quizlet?
Evidence for the Endosymbiotic Theory. – Chloroplasts and mitochondria have their own genetic code and can reproduce. – Chloroplasts and mitochondria have their own cell membranes. – Chloroplasts and mitochondria can survive on their own outside of a cell.
What evidence exists that supports the endosymbiotic theory quizlet?
What evidence exists to support the endosymbiotic origins of eukaryotic cells? The endosymbiotic theory is based on mitochondria and chloroplasts of eukaryotes. Both structures have characteristics (such as their own DNA and the ability to self-replicate) of independent prokaryotes.
What evidence helps supports the endosymbiosis theory quizlet?
Evidence in support of the endosymbiotic theory includes: the presence of 70S ribosomes in mitochondria and chloroplasts. a single membrane enclosing the mitochondria and chloroplasts.
Which discovery supported the endosymbiotic theory?
Answer and Explanation: The discovery of independent DNA (from the host) in mitochondria and chloroplasts supports the endosymbiotic theory.
Which of the following evidence supports the hypothesis for the endosymbiotic origin of eukaryotes?
Therefore gene expression similar to the bacterial system can be regarded as evidence that supports the endosymbiotic theory of the origin of eukaryotic cells from prokaryotic cells.
Which of these is the best evidence to support the endosymbiont theory?
Answer. The strongest piece of evidence for the endosymbiotic theory is the fact that mitochondria and chloroplasts have their own circular DNA, prokaryote fashion, and can still replicate, transcribe and translate some proteins. Their ribosomes are also fashioned as a prokaryotes would be.
Is endosymbiosis still occurring today?
Today, the sheer abundance of endosymbiotic relationships across diverse host lineages and habitats testifies to their continued significance.
Do endosymbiotic relationships still exist today?
Endosymbiotic relationships still do exist today as they are part of evolution. As we know, this kind of relationship involves one cell not being able to live without another. We can see this kind of behavior with bacteria.
What evidence supports the theory that eukaryotes evolved from prokaryotic cells?
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
What existing evidence supports the theory that mitochondria are of prokaryotic origin?
What existing evidence supports the theory that mitochondria are of prokaryotic origin? The endosymbiotic theory supports the statement that mitochondria are prokaryotic origin. The mitochondria multiplies similar to how bacteria (prokaryotes) multiply during binary fission.
