- Based on decades of accumulated evidence, the scientific community supports Margulis's ideas: endosymbiosis is the best explanation for the evolution of the eukaryotic cell. What's more, the evidence for endosymbiosis applies not only to mitochondria, but to other cellular organelles as well. Chloroplasts are like tiny green factories within plant cells that help convert energy from sunlight into sugars, and they have many similarities to mitochondria.

The Endosymbiosis Theory: Evolution of Cells Now that we know about both prokaryotic and eukaryotic cells, let's look at the endosymbiosis theory. This theory suggests that mitochondria and plastids in eukaryotic cells were once independent prokaryotic cells.

Explain the endosymbiotic theory of the origin of eukaryotic cells.? Best Answer: Endosymbiosis is the idea that certain organelles found in eukaryotic cells today, like mitochondria and chloroplasts were originally separate organisms which were absorbed into early eukaryotic cells and had a symbiotic relationship with them.xplain the endosymbiotic theory of the origin of eukaryotic cells and discuss an example of evidence supporting this theory.

What Evidence Supports the Theory of Evolution? Because lots of evidence supports scientific theories, they are usually accepted as true by a majority of scientists. Here’s a brief summary of the evidence that supports the theory of evolution by natural selection: Biochemistry is the study of the basic chemistry and processes that occur in cells. The biochemistry of all living things on Earth is incredibly similar, showing that all of Earth’s organisms share a common ancestry.

- From Wikipedia, the free encyclopedia. A representation of the endosymbiotic theory. An endosymbiont is any organism that lives within the body or cells of another organism, i.e. forming an endosymbiosis (Greek: ἔνδον endon within, σύν syn together and βίωσις biosis living).

- Symbiogenesis, or endosymbiotic theory, is an evolutionary theory that explains the origin of eukaryotic cells from prokaryotes.It states that several key organelles of eukaryotes originated as a symbiosis between separate single-celled organisms.ccording to this theory, mitochondria, plastids (for example chloroplasts), and possibly other organelles representing formerly free-living bacteria (prokaryotes) were taken inside another cell as an endosymbiont around 1.5 billion years ago.

Symbiogenesis The theory holds that mitochondria, plastids such as chloroplasts, and possibly other organelles of eukaryotic cells represent formerly free-living prokaryotes taken one inside the other in endosymbiosis, around 1.5 billion years ago.

Endosymbiosis Examples are: 1  Rhizobia: nitrogen-fixing bacteria which live in root nodules on plants of the pea family.  Singly-celled forams which include a single-celled alga inside the cell. This is 'facultative', which means they may or may not do it. A more far-reaching version is idioplastic endosymbiosis.

What Is Endosymbiosis? As the University of California - Berkeley explains, the evidence for endosymbiosis lies in the observation that mitochondria have both their own cell membranes and their own circular DNA genome. Mitochondria also reproduce separately from their host cells, and if a cell's mitochondria are removed, the cell cannot build new ones from scratch.

- Endosymbiotic theory. The endosymbiotic theory concerns the origins of mitochondria and chloroplasts, which are organelles of eukaryotic cells. According to this theory, these originated as prokaryotic endosymbionts, which came to live inside eukaryotic cells.he theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes).

Endosymbiotic Theory and others -New mitochondria and plastids are formed only by a process similar to binary fission -Internal structure and biochemistry of plastids is similar to cyanobacteria What are some key evolutionary changes in the eukaryote cell that allowed for endosymbiosis?

Structural Biochemistry/The Endosymbiotic Theory The endosymbiotic theory deals with the origins of mitochondria and chloroplasts, two eukaryotic organelles that have bacteria characteristics.Mitochondria and chloroplasts are believed to have developed from symbiotic bacteria and, more specifically, cyanobacteria.hese observed characteristics of both, mitochondria and chloroplast, are heart of the Endosymbiotic Theory. A comaparison in chloroplasts and Mitochondria: Both chloroplasts and mitochondria generate ATP by chemiosmosis, but they use different sources of energy. Mitochondria transfer chemical energy from food to ATP.

Evidence for the Endosymbiotic Hypothesis Since the symbiotic hypothesis states that mitochondria and chloroplasts arose from bacteria entering a eukaryotic cell to form a symbiotic relationship, similarities between bacteria and these semiautonomous organelles show strong evidence that this hypothesis is correct. 1  Function.itochondria, chloroplasts, and prokaryotes (bacteria) range from about one to ten microns in size. (1 micron=1X10 -6 Meters) This seems very basic, but if there was a large difference in sizes between these three components, the hypothesis would appear to be false.

Endosymbiont An endosymbiont or endobiont is any organism that lives to mutual benefit within the body or cells of another organism, i.e. in an endosymbiosis. Examples are nitrogen-fixing bacteria, which live in root nodules on legume roots, single-cell algae inside reef-building corals, and bacterial endosymbionts that provide essential nutrients to about 10–15% of insects. Many instances of endosymbiosis are obligate; that is, either the endosymbiont or the host cannot survive without the other, such ...

Structural Biochemistry/Cell Organelles/Peroxisome Studies have shown that: (39–58%) of peroxisome are of eukaryotic origin (13–18%) are enzymes from the mitochondria. This lead to the conclusion that it did not have a endosymbiotic origin, but rather it used proteins from other eukaryotic cells.

What is the endosymbiotic theory of the origin of eukaryotic cells? Report Abuse. The endosymbiotic hypothesis explains the origins of eukaryotic organelles like the mitochondrion and chloroplast. There is much evidence that suggests that those organelles descended from prokaryotic cells that were engulfed by a eukaryote as an endosymbiont.est Answer: The endosymbiotic theory concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

Endosymbiont Many instances of endosymbiosis are obligate; that is, either the endosymbiont or the host cannot survive without the other, such as the gutless marine worms of the genus Riftia, which get nutrition from their endosymbiotic bacteria. The most common examples of obligate endosymbioses are mitochondria and chloroplasts.he single most convincing evidence of the descent of organelles from bacteria is the position of mitochondria and plastid DNA sequences in phylogenetic trees of bacteria. Mitochondria have sequences that clearly indicate origin from a group of bacteria called the alphaproteobacteria.

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.he 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 repl … icate, transcribe and translate some proteins. Their ribosomes are also fashioned as a prokaryotes would be.

- Some of the evidence for this idea, called the Endosymbiotic Theory, is that both mitochondria and chloroplasts have their own DNA that codes for some of the proteins necessary for cellular respiration and photosynthesis. This DNA is circular, just like that seen in prokaryotic cells.
