An amoeba-like organism engulfed prokaryotes, and they eventually became cells, one inside the other

Answer 1

The correct response that best demonstrates endosymbiosis in modern cells is:

An amoeba-like organism engulfed prokaryotes, and they eventually became cells, one inside the other.

This concept refers specifically to the endosymbiotic theory, which suggests that certain organelles, like mitochondria and chloroplasts, originated from free-living prokaryotes that were engulfed by ancestral eukaryotic cells. Over time, these engulfed prokaryotes established a mutually beneficial relationship with their host cells, evolving into essential organelles.
