The concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.
<h3>What is the endosymbiotic theory?</h3>
The endosymbiotic theory is a well-sustained theory in biology about the origin of eukaryotic cells.
According to this theory, eukaryotic cells emerged by endosymbiosis between primitive eukaryotic cells and bacteria that converted into mitochondria and chloroplast organelles.
The endosymbiotic theory is well sustained in several scientific observations such as the existence of DNA in mitochondria and chloroplasts that is independent of nuclear DNA, the size of ribosomal units, etc.
In conclusion, the concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.
