The Endosymbiotic Theory


Related Questions

I believe you are referring to the Endosymbiotic theoryby Lynn Margulis. She came up with the theory that states that eukaryotic cells engulfed smaller bacteria and over time, they became specialized organelles within eukaryotic cells.

Yes, they do - this is one piece of evidence used to support the endosymbiotic theory. This states that Eukaryotic cells arose from Prokaryotic cells that engulfed other Prokaryotic cells. The DNA found in mitochondria and chloroplasts is similar in size and shape (circular) to that of bacteria.

The theory of endosymbiosis states that eukaryotic cells evolved when some prokaryotes were engulfed by others and avoided being digested. The theory states that chloroplasts developed from photosynthetic bacteria and mitochondria from aerobic bacteria. Evidence in support of the endosymbiotic theory includes: 1) The inner membranes of chloroplasts and mitochondria have enzymes and transport systems similar to those found in bacteria 2) They reproduce themselves by splitting into two, similar to the process of binary fission in bacteria 3) They contain circular DNA molecules which are not combined with proteins, like bacteria and unlike the eukaryotic DNA in the nucleus 4) They have their own ribosomes, which are more like bacterial ribosomes than eukaryotic ones.

The theory about the origin of mitochondria states that they used to be bacteria that developed a symbiotic relationship other cells.

A mitochondrion is itself an organelle. However, it does contain its own ribosomes. Ribosomes are regarded as organelles when they occur either free in the cytoplasm or attached to the rough endoplasmic reticulum. The theory of the endosymbiotic origin of mitochondria (and chloroplasts) states that mitochondria are descendants of free-living prokaryotic cells (bacteria). Bacteria contain ribosomes, and so do mitochondria and chloroplasts.

Chloroplasts and mitochondria are similar in that they both maintain some autonomy from the cell. They both contain their own genetic material separate from the nucleus of the cell. This has lead to the endosymbiotic theory - which states that chloroplasts and mitochondria were once unicellular organisms engulfed by and then incorporated into another cell.

Endosymbiotic theory describes that.It shows photosynthetic and aerobic bacteria engulfed by eulariyotic cells turned into chloroplst and mitochondria.

Plesiomorphy. Shared '' primitive '' characteristics of the ancestor or outgroup of a clade.

Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNATo provide some autonomy for its function the mitochondria have their own DNA. One cell theory states that some bacteria invaded the cell and established a symbiotic relationship. Mitochondria and chloroplasts are such microbes establishing permanent symbiotic relationship with the plant cell.

Eukaryotes evolved from a process call endosymbiosis. Endosymbiosis states that eukaryotes started as two separate bacterium. The bigger bacteria engulfed the smaller. This is how the mitochondria is enclosed in the cell. There is evidence of this because the mitochondria has its on cell membrane and contains its own DNA.

The endosyymbiotic theory stated that the mitochondria formed through the endosymbiosis of a proteobacteria. It also states that chloroplast formed from the endosymbiosis of a cyanobacteria.

yes , nag is belonging to st community. it the Indian primitive ancient civilization which was basically founded in Odisha then it spread in the other states.

There is a theory. This theory states that mitochondria and chloroplasts were once a free living bacterias(prokaryote) long time ago. People thought this because mitochondria and chloroplasts are not like other organelles of the cell. They divide independently during cell division, they both have their own DNA, and even those DNAs (known as mtDNA) replicates.

Thomas Jefferson believed that American Indians were primitive people who could become civilized with the proper exposure to culture. Thomas Jefferson was the 3rd President of the United States.

The cellularization theory states that a unicellular organism would have developed from membrane boundaries/partitions around each nuclei from a single celled organism with multiple nuclei. Protists like ciliates and slime molds have multiple nuclei supporting this theory.

If you've ever watched the show "Dual Survival " Cody the shorter blond haired survivalist states that his mitochondria is very strong in the bottom of his feet because he never wares shoes ,and as we know on a survivalist show they always drop the people off at harsh and wild places all over the world and Cody exposes his bare skin on the bottom of his feet to the cold snow , burnig deserts , dangerous grounds of Africa,and the mitochondria is said to be strong in his feet allowing him to have tofer feet then the average male

In the 1700s, schools for children in the United States colonies were still fairly primitive. Classrooms were made up of many different ages so coursework was seldom targeted for the right age groups.

Yes, but they tend to be the primitive defense mechanisms; denial, minimization, rationalization and projection. Higher order defense mechanisms, such as humor, altruism, and sublimation, or even defenses such as intellectualization, are not operative, however, in delusional/psychotic states.

According to the endosymbiotic theory of the origin of both chloroplasts and mitochondria, the ancestors of these two organelles were free-living prokaryotic cells.This theory states that an early eukaryotic cell engulfed a prokaryotic cell by endocytosis, much as one of our phagocytic white blood cells engulfs a bacterium.On this occasion, however, for some reason (a mutation having changed a protein on the surface of the smaller cell, perhaps?) the prokaryote was not digested, but remained in a structure which evolved into the modern chloroplast, whose outer membrane was the infolded eukaryotic one, and with an inner membrane representing the original prokaryotic plasma membrane. This particular prokaryote was, unlike the larger cell, capable of photosynthesis.In this relationship, both species benefited. The larger cell gained the ability to synthesize its own organic compounds from inorganic ones, and the smaller cell no longer had to search for protection or inorganic nutrients.The same theory assigns the origin of mitochondriato a similar, much earlier, event involving the engulfing of an aerobic prokaryote by a larger cell."Endosymbiosis" refers to the relationship between two species (symbiosis) in which one is inside (endo-) the other.Evidence for the theory includes:the size and shape of the organelles;their possession of a surrounding double membrane, the outer membrane more eukaryotic and the inner more prokaryotic in chemistry;the presence of DNA in both organelles, in the form of a circular molecule lacking associated proteins, with genes, transcription, and translation;the presence in both organelles of ribosomes that are similar in size to prokaryotic ones;the division by both organelles in a manner like binary fission.

It depends where you are. In the United States, the bacteria would fall into 1 of 2 different kingdoms. Modern day bacteria fall into the Kingdom "Bacteria" where as their more primitive ancestors fall into the "Archaea" Kingdom. In other places of the world such as the UK they would fall into the Kingdom referred to as "Prokaryota" or "Monera"

They were vastly different. The US is a large unified country with central government and modern technology. The Greek world consisted of hundreds of independent city-states scattered around the Mediterranean and Black Seas in the midst of alien populations, and with a wide range of types of government, and primitive technology.

None. The Hammurabi's code was was to ancient, primitive and obsolete to be of any use for the United States. However, the code did influence other codes and the other codes influenced yet other codes and so on until eventually the Roman code of law came about. The Roman code of law influenced the US code quite a bit. So what you are saying is that the Hammurabi code did eventually influnece US laws.
