Answer 1

pick one of the provided answers

Answer 2

The central concept of endosymbiosis theory is that larger cells engulf smaller cells, leading to a symbiotic relationship. This theory suggests that some organelles, such as mitochondria and chloroplasts, originated from free-living prokaryotic cells that were engulfed by ancestral eukaryotic cells. Over time, these engulfed cells became integral parts of the host cells, leading to the complexity of modern eukaryotic organisms.

Answer 3

The correct choice is: **Larger cells engulf smaller cells, leading to symbiosis.**
