An endosymbiont or endobiont is any organism that lives within the body or cells of another organism, i.e. forming an endosymbiosis
The endosymbiont theory is associated with mitochondria and chloroplasts. It proposes that these organelles originated from primitive prokaryotic cells that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
Both of them are thought to have originated from primitive bacteria. This theory is called Endosymbiont theory.

The endosymbiont theory proposes that organelles like mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by a host cell and developed a symbiotic relationship. This has implications for phylogeny as it suggests that certain organelles have a different evolutionary history than the rest of the cell, leading to the concept of lateral gene transfer and complicating the interpretation of evolutionary relationships based on traditional phylogenetic methods.
Schleiden, Schwann, and Virchow are all three associated with the cell theory.
