To correctly address your question, it would be helpful if you provided the specific statements or options you're considering about how mitochondria were acquired by host cells. However, I can share general information regarding the acquisition of mitochondria:
Mitochondria are thought to have been acquired by ancient eukaryotic cells through a process known as endosymbiosis. This theory suggests that a primitive eukaryotic cell engulfed a free-living prokaryotic organism, likely an alpha-proteobacterium, which then became an integral part of the host cell. Over time, the engulfed prokaryote lost much of its independent functionality and transferred many of its genes to the host's nuclear genome, resulting in the modern mitochondrion that is crucial for energy production in eukaryotic cells.
This process is well-supported by evidence showing that mitochondria have their own DNA (mtDNA), which is similar to bacterial DNA, and they replicate independently of the cell's nuclear DNA.
If you have specific statements you would like to compare or inquire about, please provide them, and I can help you determine which are true based on the endosymbiotic theory.
