Endosymbiosis

A theory that explains the origin of eukaryotic cells from prokaryotic organisms, through a symbiotic relationship.

Mitochondrion

A membrane-bound organelle found in most eukaryotic cells, responsible for cellular respiration and energy production.

Engulfing Vesicle

A membrane-bound vesicle that forms to engulf particles, bacteria, or other materials into a cell by phagocytosis.

Final Answer :
A
Explanation :
The outer mitochondrial membrane represents the engulfing vesicle because it has the same lipid composition as the plasma membrane of the host cell that engulfed the ancestor of the mitochondrion. This supports the hypothesis that the mitochondrion originated from endosymbiosis of an aerobic prokaryote inside a larger eukaryotic host cell.
