- Concept: The theory of endosymbiosis proposes that early ancestral eukaryotic cells engulfed free-living aerobic and photosynthetic prokaryotes, forging an obligate mutualistic relationship [cite: 13, 15].
- Skill: FRQ Task Verb "Describe" — Describe the specific morphological and molecular evidence (double membranes, circular DNA, unique ribosomes) that strongly supports the endosymbiotic origins of mitochondria and chloroplasts [cite: 13, 15, 22].
- Concept: Explain how eukaryotic cells utilize internal membranes to partition the cell into specialized functional regions.
