Answer 1

2. **Metaphase:** Sister chromatids attach to spindle fibers at their centromeres.3. **Prophase:** Chromosomes condense and become visible as distinct structures.4. **Telophase/Cytokinesis:** A cleavage furrow (in animal cells) or cell plate (in plant cells) forms, dividing the cytoplasm.5. **Metaphase:** Sister chromatids align at the cell's equator (metaphase plate).6. **Interphase (S phase):** DNA replication occurs, duplicating the chromosomes.7. **Prophase:** The nucleolus disappears as the nucleus prepares to break down.8. **Anaphase:** Sister chromatids separate and move to opposite poles of the cell.9. **Interphase (G1 phase):** The cell grows in size and increases its organelle and enzyme content.10. **Prometaphase (Late Prophase):** The nuclear membrane fragments, allowing spindle fibers to interact with chromosomes.11. **Telophase:** The nuclear membrane reforms around each set of chromosomes, and the nucleolus reappears.12. **Interphase (G2 phase):** The cell synthesizes proteins and structures needed for cell division.13. **Cytokinesis:** The division of the cytoplasm, completing cell division. While it often overlaps with telophase, it is a distinct process.14. **Prophase:** Centrioles (in animal cells) begin migrating to opposite poles of the cell, establishing the poles of the spindle apparatus.
