Endosymbiotic origin suggests that organelles like mitochondria and chloroplast originated from $\bf Purple~Sulphur~bacteria$ or prokaryotic cells, because these organelle are similar to prokaryotic cells in following ways

$\square$ Structure of DNA and DNA sequences
$\square$ Type of ribosome (70s)
$\square$ Sensitivity of Antibiotic chloremphenicol with protein synthesis.
$\square$ Both divide by amitosis.
