Instructions
Match each description below to the correct phase of the cell cycle. Write the corresponding letter in the blank space provided. Some letters will be used multiple times.
A Prophase
B Metaphase
C Anaphase
D Telophase
E Cytokinesis
1. Chromatin condenses into tightly coiled, visible chromosomes.
2. Sister chromatids are pulled apart toward opposite poles of the cell.
3. A cleavage furrow pinches the animal cell membrane into two identical cells.
4. Chromosomes line up single-file along the equator of the cell.
5. Nuclear envelopes reform around two new sets of genetic material.
6. The spindle fibers disassemble as the chromosomes reach the poles.
7. Spindle fibers attach to the kinetochores of each sister chromatid.
8. In plant cells, a cell plate forms to divide the cytoplasm.
9. The nucleolus disappears and the nuclear envelope begins to break down.
10. This is the shortest phase of the mitotic process.
11. Centrosomes move to opposite ends of the cell to form poles.
12. Chromosomes begin to de-condense back into chromatin.
13. The cytoplasm is physically partitioned into two distinct volumes.
14. The "metaphase plate" is established at the cell's midpoint.
15. Individual chromatids are now officially recognized as chromosomes.
16. Mitotic spindle fibers first begin to grow from the centrosomes.
17. Two distinct nuclei are visible within the same, elongated cell.
18. This phase ensures each daughter cell receives one copy of every chromosome.
19. Nucleoli reappear within the newly formed nuclear envelopes.
20. The cell elongates as non-kinetochore spindle fibers push against each other.
21. Chromosomes are at their most condensed and easily visible state.
22. Results in the creation of two genetically identical daughter cells.
23. Often occurs simultaneously with the final phase of mitosis.
24. The centromeres split, allowing sister chromatids to separate.
25. DNA synthesis has been completed before this phase starts.

Visualizing the mechanics of Prophase through Cytokinesis
Biology Series 02
Stage 01
Prophase
- Chromatin condenses into visible chromosomes
- Nucleolus disappears and envelope breaks down
- Centrosomes move to opposite poles
- Mitotic spindle begins to form
MICROSCOPIC VIEW: EARLY CONDENSATION
Stage 02
Metaphase
- Chromosomes align on the metaphase plate (equator)
- Centrosomes are at official opposite poles
- Spindle fibers from each pole attach to kinetochores
MICROSCOPIC VIEW: EQUATORIAL ALIGNMENT
Stage 03
Anaphase
- Centromeres split as sister chromatids separate
- Each chromatid becomes a full chromosome
- Microtubules shorten, pulling chromosomes to poles
- Cell elongates via non-kinetochore fibers
MICROSCOPIC VIEW: RAPID SEPARATION
Stage 04
Telophase
- Two daughter nuclear envelopes reform
- Nucleoli reappear in each nucleus
- Chromosomes de-condense into chromatin
- Mitotic spindle is disassembled
MICROSCOPIC VIEW: NUCLEAR REFORMATION
Final Step
Cytokinesis
Animal Cells
A cleavage furrow pinches the cell into two separate volumes.
Plant Cells
A cell plate forms down the middle, eventually creating a new cell wall.
