Where do scientists believe mitochondria and chloroplasts originated?

Scientists believe that mitochondria and chloroplasts originated from ancient prokaryotic cells through a process called endosymbiosis. This theory proposes that mitochondria were once free-living bacteria that were engulfed by a primitive eukaryotic cell, forming a symbiotic relationship. Similarly, chloroplasts are thought to have originated from ancient photosynthetic bacteria that were also engulfed by a eukaryotic cell.


Are both chloroplasts and mitochondria bounded by two membranes?

Yes. The outer membrane is similar to modern eukaryotic membranes, such as the plasma membranes of animals and plants. The inner membrane is similar to modern prokaryotic membranes, found in bacteria. This difference has been taken as one piece of evidence to support the theory of the endosymbiotic origin of these two organelles, i.e. the idea that each of these organelles formed originally from the engulfing of a prokaryotic cell by a eukaryotic one.


The endosymbiotic theory includes all of the following except?

The endosymbiotic theory includes the idea that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by larger cells and developed a symbiotic relationship, leading to modern eukaryotic cells. It does not include the concept of gene flow between mitochondrial and nuclear genomes.


Did mitochondria evolved from engulfed prokaryotes?

Yes, mitochondria are believed to have evolved from engulfed aerobic bacteria that formed a symbiotic relationship with early eukaryotic cells. This theory is known as the endosymbiotic theory and is supported by similarities between mitochondria and modern-day bacteria, such as their own DNA and ability to replicate independently.


When did mitochondria first live?

Mitochondria are believed to have first evolved around 1.5 to 2 billion years ago from a symbiotic relationship between ancient prokaryotic organisms and the ancestors of modern eukaryotic cells. This event is known as endosymbiosis and played a crucial role in the evolution of complex life forms on Earth.

Which do chloroplasts and mitochondria have that other organelles lack?

There is a theory that chloroplast and mitochondria were independent organisms. Since they were, they would have their own DNA. And it is true that they do. It is interesting that you get your mitochondria from only your mother. There are many studies have used mtDNA to trace the evolution and migration of human species, including when the common ancestor to modern humans and Neanderthals lived.


Does an animal mitochondrion contain functional ribosomes?

Yes, chloroplasts, like mitochondria, contain ribosomes.Chloroplasts also contain DNA, and synthesize messenger RNA by transcription. Polypeptides are formed at the ribosomes.These ribosomes are more or less like those of modern prokaryotic cells; this is one of the facts that supports the theory that chloroplasts and mitochondria evolved from ancestral free-living prokaryotic organisms.

Which eukaryotic kingdom includes members that are the result of endosymbioses that included an ancient proteobacterium and an ancient cyanobacterium?

The eukaryotic kingdom that includes members resulting from endosymbiosis with an ancient proteobacterium and an ancient cyanobacterium is Plantae. This process led to the formation of chloroplasts in plant cells, providing them with the ability to perform photosynthesis.

Is it true mitochondria and chloroplasts originated in bacteria?

It is thought that chloroplasts and mitochondria were prokaryotic organisms and they were engulfed by a eukaryotic organism and instead of being digested by the cell a symbiotic relationship was formed. this is called endosymbiosis. the first scientist to pioneer this kind of thinking was Mereschkowsky back in 1905. Taking chloroplast as the example, most of the genes from the chloroplast genome have been intergrated into the nulcear genome. Those that are left are conserved in both the chloroplast genome and the cyanobacteria genome. (the cyanobacteria is the prokaryotic organisms that is thought to have been engulfed, thus creating the ancestor to the modern chloroplast). For example, the gene for bacterial cell division is also found in the chloroplast genome. Comparing both the modern chloroplast genome and the modern cyanobacteria genome it is possilbe to see just how many genes that where originally chloroplast based have jumped ship and gone to the nuclear genome. Both animals and plants contain mitochondria but only plants contain chloroplasts. This suggests that the endosymbiotic relationship between the eukaryotic cell and the mitcohondria happen before the animal and plant lines diverged.


What is the modern version of prokaryotes?

The modern version of prokaryote cells are called eukaryotic cells.


What is the modern version of prokaryote cells called?

The modern version of prokaryotic cells is called bacteria or archaea. These cells lack a true nucleus and other membrane-bound organelles.


Is evidence for the endosymbiont theory explaining the origin of mitochondria and chloroplasts?

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.


From where did eukaryotes evolve?

Eukaryotes are believed to have evolved from prokaryotic cells through a process known as endosymbiosis. This theory suggests that an ancestral eukaryotic cell engulfed a primitive prokaryotic cell, which eventually developed into the mitochondria and chloroplasts found in eukaryotic cells today.
