The endosymbiotic theory states that:

• mitochondria and chloroplasts originated as free-living prokaryotes that were engulfed by a host cell.

• all organelles in eukaryotic cells originated from prokaryotic cells.

• eukaryotic cells evolved from archaea.

• prokaryotic cells evolved from eukaryotic cells.

According to the endosymbiotic theory, certain kinds of prokaryotes evolved into:

• mitochondria and chloroplasts

• nucleus

• ribosomes

• cell membrane

Which of the following best describes the endosymbiotic theory?

• Prokaryotes evolved independently.

• Prokaryotes began living inside larger cells and evolved into organelles.

• Eukaryotes evolved into prokaryotes.

• Prokaryotes and eukaryotes are unrelated.

The Miller-Urey experiment demonstrated:

• the synthesis of organic compounds from inorganic precursors

• the theory of evolution

• the structure of DNA

• the principles of quantum mechanics
