Mitochondria and plastids are the two cell organelles in eukaryotic cells that possess their own genetic material (DNA).

This characteristic supports the endosymbiotic theory, which suggests that these organelles originated from prokaryotic organisms engulfed by primitive eukaryotic cells.

The DNA in mitochondria and plastids is typically circular, similar to bacterial DNA, and they also have their own ribosomes and protein synthesis machinery. Endoplasmic reticulum, lysosomes, and Golgi apparatus are part of the endomembrane system and do not have their own DNA.
