A Levels Biology (9700)•9700/12/M/J/18

Explanation
Only statement 2 is always true about cytokinesis Steps:
- Identify cytokinesis as the cytoplasmic division following nuclear division in mitosis or meiosis.
- Evaluate statement 1: It likely describes animal-specific features like cleavage furrow, which isn't universal.
- Evaluate statement 2: It must refer to a core process, such as actin-myosin ring contraction or vesicle fusion, occurring in all eukaryotes.
- Evaluate statement 3: It probably mentions plant-specific cell plate formation, not always applicable. Why C is correct:
- Cytokinesis universally involves cytoplasmic partitioning, and statement 2 aligns with this definition across cell types. Why the others are wrong:
- A includes all, but 1 and 3 are not universal.
- B omits 2 but includes non-universal 1 and 3.
- D ignores 1 and 2, focusing only on non-universal 3.
Final answer: C
