Question

“Endo” means “internal” or “within.” “Symbiosis” means “a mutually beneficial relationship.” How do modern cells demonstrate endosymbiosis?(1 point) Responses Cells benefit from one another by providing different functions and are found within organ systems of the body. Cells benefit from one another by providing different functions and are found within organ systems of the body. An amoeba-like organism engulfed prokaryotes, and they eventually became cells, one inside the other. An amoeba-like organism engulfed prokaryotes, and they eventually became cells, one inside the other. Cells are inside the body and work together to function as a whole organism. Cells are inside the body and work together to function as a whole organism. Organelles are inside cells and provide cells with energy and proteins, while the cellular membrane shelters the organelles.

Answer 1

The response that best illustrates how modern cells demonstrate endosymbiosis is: **"An amoeba-like organism engulfed prokaryotes, and they eventually became cells, one inside the other."**

This statement reflects the endosymbiotic theory, which posits that certain organelles in eukaryotic cells, such as mitochondria and chloroplasts, originated from prokaryotic cells that were engulfed by an ancestral host cell. Over time, these engulfed prokaryotes became integral parts of the eukaryotic cell, establishing a mutually beneficial relationship.
