Answer:
Mutualistic endosymbiosis, genomic DNA, act as organelle.
Explanation:
Mutualistic endosymbiosis theory the most important scientific theory in evolution of organelles from prokaryotes. Just like a parasite these mitochondria and chloroplasts were living inside the prokaryotes (host) through endocytosis. Eventually they got adapted and developed their own DNA. Apart from nucleus, mitochondria and chloroplast are the only two organelles that have their own genomic DNA. Chloroplast contains mitochondria and need them for ATP production. Endosymbioants cant live outside host and now becomes an organelle.
