Which one of the following is not true about the membrane invagination hypothesis?
Correct answer: D. The second membrane dissolves
- A. Formation of the endomembrane system
- B. Membrane modification
- C. Second membrane for protochloroplast
- D. The second membrane dissolves
Explanation
The membrane invagination hypothesis describes the process by which the internal membranes of eukaryotic cells, such as the endoplasmic reticulum and nuclear envelope, evolved through the invagination of the plasma membrane of a prokaryotic ancestor. This hypothesis supports the formation and specialization of membranes into complex organelles. Option D, 'Second membrane dissolves,' is incorrect as it contradicts the hypothesis's emphasis on membrane formation rather than dissolution. Options A, B, and C accurately describe aspects of the hypothesis, focusing on the creation and specialization of internal membranes.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
