vious

Answer 1

Mitochondria

Step-by-step explanation:

I would say mitochondria because without this, how would energy be produced?

Answer 2

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
