Endosymbiotic Theory | Other Quiz - Quizizz

C) The endosymbiosis theory tells us how the eukaryotic cell first arose. E) Strong evidence in support of the theory is that the DNA of chloroplasts and mitochondria is very closely related to DNA sequences from 2 different groups of bacteria.Biologist Lynn Margulis first made the case for endosymbiosis in the 1960s, but for many years other biologists were skeptical. It turns out that many lines of evidence support this idea. Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondriaTranscribed Image Text from this Question. Which of these statements are both true and support the endosymbiosis theory? These cookies are necessary for the website to function and cannot be switched off in our systems. They are usually only set in response to actions made by you which...This is facilitated by the fact that in most cases the relationship benefits both the organisms unlike a parasitic relationship where one feeds off the other. Endosymbiosis is also the case with bacteria that live in the digestive system of animals and the nitrogen fixing bacteria that live in plants.Evidence has been found to support the idea. This shows that the plastid regeneration relies on an extracellular source, such as from cell division or endosymbiosis. * They are surrounded by two or more membranes, and the innermost of these shows differences in composition from the other...

Evidence for endosymbiosis

Both of these organelles have their own DNA and their own ribosomes that do not match the rest of the cell. This indicates that they could survive and reproduce on their own. Before these prokaryotes were able to undergo endosymbiosis, they first most likely had to become colonial organisms.The endosymbiotic theory states that mitochondria and chlopoplasts in today's eukaryotic cells were once Briefly describe what is meant by the endosymbiotic theory. Give some evidence supporting the Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the...The endosymbiosis theory was advocated especially by Lynn Margulis. She has also launched a more general variant, the Symbiogenesis theory, which But the accepted part of her endosymbiosis theory holds that mitochondria and chloroplasts are invaded bacteria. There are a lot of problems with...This article explains the basic principles of endosymbiotic theory, including the concept of secondary endosymbiosis, in which the plastids of some algal groups arose through Much of the evidence for the endosymbiotic theory comes from the structure and handling of these organelles' genetic codes.

Transcribed Image Text from this Question. Which of these statements are both true and support the endosymbiosis theory? Select all that apply. Most mitochondrial genes are transcribed unidirectionally. Organelle DNA packaging is similar to the packaging of a bacterial chromosome.The endosyymbiotic theory stated that the mitochondria formed through the endosymbiosis of a proteobacteria. It is theorised that these began as small, independent prokaryotes. Some evidence in support of this theory includes that both mitochondria and chloroplasts have their own DNA, and...Endosymbiosis is the term modern scientists use for how the... In this case, scientist believe the pre-eukaryotic cell may have been an archaeal cell which started to develop Both are debated to be the true ancestor of the alphaproteobacteria that entered into the endosymbiotic relationship with the...Both of these novel pathways led to organisms that could reproduce at a higher rate than standard bacteria. One cell living inside of another is called endosymbiosis if both organisms benefit, hence the Endosymbiotic theory is supported by a large body of evidence. The general process can be...This article states that: "The endosymbiont theory of mitochondria and chloroplasts was proposed by Lynn Margulis." This is not true. Fixed the flagella not being thought to result from endosymbiosis (which is false). A lot of the info is only half true or big generalisations, which I might fix later if I can...
