What is the central concept of endosymbiosis theory? Cells are static and unchanging. Cells only evolve from non-living matter. Larger cells engulf smaller cells, leading to symbiosis.

Answer 1

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.
