Question
The diagram illustrates various phases of the cell cycle, including stages of mitosis. The cells are not displayed in the sequential order of the cell cycle. Below, the diagram is used to respond to several questions:

**Diagram Labels:**

- **Cell A:** Depicts two large structures within the cell, one of which is labeled "X".
- **Cell B:** Shows chromosomes aligned along the equator of the cell.
- **Cell C:** Displays chromosomes being pulled apart toward opposite poles.
- **Cell D:** Contains a nucleus with visible chromatin.
- **Cell E:** Shows chromatids moving towards cell poles.
- **Cell F:** Depicts separated chromatids reaching the cell poles with a visible cleavage furrow.

**Questions:**

a. **Which cell is in metaphase?**

b. **Which cell is in the last phase of Mitosis?**

c. **In cell A, what structure is labeled X?**

d. **Which cell depicts the stage of mitosis that occurs prior to telophase?**

e. **List the cell diagrams in order from first to last appearance in the cell cycle.**

f. **Which of the cells, if any, is not part of mitosis?**

**Diagrams Explained:**

- **Metaphase (Cell B):** Chromosomes align at the cell's equatorial plane, preparing to separate.
- **Last Phase of Mitosis (Telophase, Cell F):** Chromatids reach opposite poles, and cell division is imminent.
- **Structure X in Cell A:** Typically represents the nucleolus or another organelle.
- **Stage Prior to Telophase (Anaphase, Cell C):** Chromatids separate and move towards opposite poles.
- **Order of Cell Cycle:**
  - 1st: Cell D (Interphase)
  - 2nd: Cell B (Metaphase)
  - 3rd: Cell C (Anaphase)
  - 4th: Cell E (Early Telophase)
  - 5th: Cell F (Telophase/Cytokinesis)
  - Cell A (likely occurring outside mitosis, e.g., Interphase)
- **Non-Mitotic Cell:** Cell A (Interphase)

This detailed overview assists in understanding cell cycle progression and identifying stages of mitosis.
