The mitochondria in eukaryotic cells originated from prokaryotic cells, bacteria that were once free-living. The mitochondria have their own DNA, which is inherited from the mother in most species. Similarly, plant cells have organelles called plastids which contain their own DNA and originated from free-living bacteria. The chloroplasts in plant cells, which convert the energy of sunlight into chemical energy via photosynthesis, are a kind of plastid, and they originated from bacteria that could do photosynthesis.

Answer from: deboerzac4809

Endosymbiotic theory

the endosymbiotic theory says that mitochondria and plastids, like the chloroplast, originated from small prokaryotic organisms that started to live inside other larger organisms, in a symbiotic relationship.

In this type of relationship,

One organism lives in an intimate association with the other. In endosymbiosis, a smaller organism, called a symbiont, lives within a larger one, The host, in a mutually beneficial relationship.The meaning of such interdependence

A eukaryotic organism is believed to comprise an autotrophic prokaryotic particle. From then on, they started a cooperative relationship, and one organism began to live inside the other (endosymbiosis). Over time, this relationship became so important that organisms could no longer live in isolation.

The autotrophic prokaryote organism probably benefited the host cell by ensuring processes such as cellular respiration, in the case of mitochondria, and photosynthesis, in the case of chloroplasts. The host cell, on the other hand, guaranteed protection and nutrients to the new cell organelles.

In short, one organism lives inside another, and one organism could no longer live without another.
