Practice Question

The theory proposed to suggest that prokaryotic species were engulfed by eukaryotic ancestors and put to work as the mitochondria is called

Answer Choices:

Correct Answer:

Endosymbiotic Theory

Rationale:

◆ The Endosymbiotic Theory proposes that mitochondria (and chloroplasts) originated when primitive eukaryotic cells engulfed prokaryotic organisms but did not destroy them.

◆ Instead, these prokaryotic cells became permanent residents, evolving into organelles that provided energy through aerobic respiration.

◆ Evidence supporting this theory includes the fact that mitochondria have their own circular DNA, ribosomes, and double membranes, which are similar to bacteria.

◆ This theory is widely accepted today as the explanation for the origin of mitochondria and chloroplasts in eukaryotic cells.
