vious

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.

Mitochondria

Explanation:

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

1. founder effect

2. evolution

3. natural selection

4. species

5. geographically isolated

Explanation: Good luck! :D
