Answer

To solve the matching question between Column I (phases of the cell cycle) and Column II (their significance), we will analyze each phase and its corresponding significance step by step.

### Step-by-Step Solution:

1. **Telophase (A)**:
- In telophase, the cell prepares to divide, and the nuclear envelope re-forms around the separated sets of chromosomes. This phase is characterized by the reformation of cell organelles, including the endoplasmic reticulum (ER).
- **Match**: Telophase (A) → Reformation of ER (iv).

2. **Anaphase (B)**:
- During anaphase, the sister chromatids are pulled apart and move toward opposite poles of the cell. This is a critical step in ensuring that each daughter cell will receive an identical set of chromosomes.
- **Match**: Anaphase (B) → Sister chromatids are broken down (iii).

3. **Metaphase (C)**:
- In metaphase, chromosomes align at the equatorial plate of the cell, and the spindle fibers attach to the centromeres of the chromosomes. This alignment is crucial for the proper separation of chromosomes during the next phase.
- **Match**: Metaphase (C) → Formation of opposite spindle poles (ii).

4. **Prophase (D)**:
- Prophase is the first stage of mitosis, where the chromatin condenses into visible chromosomes, and the spindle apparatus begins to form. The spindle fibers grow from the centrosomes toward the chromosomes.
- **Match**: Prophase (D) → Spindle grows between the centrosomes (i).

### Final Matches:
- A → iv (Telophase → Reformation of ER)
- B → iii (Anaphase → Sister chromatids are broken down)
- C → ii (Metaphase → Formation of opposite spindle poles)
- D → i (Prophase → Spindle grows between the centrosomes)

### Summary of Matches:
- A - iv
- B - iii
- C - ii
- D - i
