Cells benefit from one another by providing different functions and are found within organ systems of the body.
Organelles are inside cells and provide cells with energy and proteins, while the cellular membrane shelters the organelles.

The correct answer is: An amoeba-like organism engulfed prokaryotes, and they eventually became cells, one inside the other.

This statement describes the concept of endosymbiosis, where certain organelles (like mitochondria and chloroplasts) are thought to have originated from prokaryotic cells that were engulfed by a ancestral eukaryotic cell, leading to a mutually beneficial relationship.
