A bacteria cell was engulfed into a host cell through the process of phagocytosis.

Answer 1

The correct statement about how mitochondria were acquired by host cells is:

**A bacteria cell was engulfed into a host cell through the process of phagocytosis.**

This is consistent with the endosymbiotic theory, which suggests that mitochondria originated from free-living bacteria that were engulfed by an ancestral eukaryotic cell. Over time, these engulfed bacteria became integral parts of the cell, evolving into mitochondria.
