Summarize the role of endosymbiosis in eukaryotic evolution.

The term evolution indicates the process by which changes appear in an organism after many generations. It takes millions of years to occur. It allows organisms to survive in nature better than their ancestors.

Endosymbiosis is a type of symbiosis in which an organism such as cyanobacteriumlives inside the host body, such as eukaryotic cells, to give a survival advantage to each other.

It is of two types: primary endosymbiosis (when eukaryotic cells engulf prokaryotic cells) and secondary endosymbiosis (when a eukaryotic cell engulf another eukaryotic cell).

Endosymbiosis helps in the process of evolution. For example, when the host cell takes up the organelle mitochondria, the energy formed in the host cell increases, which helps the particular eukaryotic cell to survive faster than neighbor cells.
