Endosymbiotic theory explains the formation of organelles surrounded by how many membranes?
Endosymbiotic theory explains the formation of organelles surrounded by two membranes. This theory suggests that eukaryotic organelles such as mitochondria and chloroplasts originated from symbiotic prokaryotic cells that were engulfed by a host cell, leading to a mutually beneficial relationship.
How mitochondria or chloroplasts evolved?
Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.
Which organelle is believed to have been a symbiont of an ancient cell?
Mitochondria are believed to have originated as symbiotic bacteria that were engulfed by ancestral eukaryotic cells. This theory is known as endosymbiosis and is supported by evidence such as the mitochondria having their own DNA and ribosomes.
How many times is chloroplast larger than mitochondria?
This is a relatively complicated question as the exact origins of mitochondria and how they came to be included in eukaryotic cells is still under investigation and therefore open to debate.Everyone seems to agree though, that they originally come from bacterium and that they were assimilated into eukaryotic cells either because they were useful or through some form of symbiosis.As mitochondria are common to both plant and animal cells it could therefore be argued that they shared a common ancestor at some point in evolution.The inclusion of the chloroplast came later, and a separate line of mitochondrial and chloroplast carrying cells evolved - eventually becoming plants. The line without the chloroplast becoming animals.
What acts like chloroplast?
Mitochondria act like chloroplasts in plants as they both generate energy for the cell through cellular respiration and photosynthesis, respectively. Both organelles have their own DNA and ribosomes, supporting the endosymbiotic theory that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by a primitive eukaryotic cell.
What concept explains the presence of mitochondria in cell?
The concept that explains the presence of mitochondria in cells is the endosymbiotic theory. Mitochondria in cells derived from the extra embryonic membranes.

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.

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.
What organelles that have a double membrane?
Nucleus Mitochondria
What explains why or how something happens?
it is a Theory! :)
The theory of modern synthesis states that evolution involves changes in a population and acirc and 128 and 153s?
The theory of modern synthesis, also known as neo-Darwinism, combines Darwin's theory of natural selection with modern genetics. It explains how evolution occurs through changes in the genetic makeup of populations over time. This theory emphasizes the role of mutations, genetic drift, gene flow, and natural selection in driving evolutionary change.
What is the theory that explains how the continents move called?
The theory is Tectonics.

Discuss evidence that supports the endosymbiotic theory of eukaryotic evolution?
1.) Mitochondria and plastids are relatively the same size as bacteria 2.) Mitochondria and plastids have nucleiod DNA molecules - just like bacteria. 3.) Mitochondria and plastids reproduce the same way as bacteria - binary fission.
