Question

name
animal and plant mitosis
match the parts of the diagrams to their names. phase labels are boxed next to each phase picture, component names are not. then, answer the questions below.
1 interphase
2 prophase
3 prometaphase
4 metaphase
5 anaphase
6 telophase
7 centrosomes
8 replicated chromosomes
9 unreplicated chromosomes
10 nuclear envelope
11 nucleolus
12 contractile ring
13 cell plate
14 spindle
15 unreplicated chromatin
16 replicated chromatin

1. which diagrams shows animal cell mitosis and which diagram shows plant cell mitosis (top or bottom)? explain how you know.

Explanation:

Step1: Match phases (top animal cell)

1. Interphase: C (cell with intact nucleus, chromatin)
2. Prophase: D (chromosomes condense, centrosomes move)
3. Prometaphase: (not labeled as a box, but component P = 7. Centrosomes)
4. Metaphase: E (chromosomes at equator)
5. Anaphase: A (chromosomes pull apart)
6. Telophase: B (two new nuclei, contractile ring O = 12. Contractile Ring)

Step2: Match phases (bottom plant cell)

1. Interphase: C (cell with intact nucleus, G = 11. Nucleolus, H = 16. Replicated Chromatin, I = 10. Nuclear Envelope, M = 7. Centrosomes)
2. Prophase: D (chromosomes condense, J = 8. Replicated Chromosomes)
3. Prometaphase: (not labeled as a box, K = 14. Spindle)
4. Metaphase: E (chromosomes at equator)
5. Anaphase: A (chromosomes pull apart)
6. Telophase: B (two new cells, N = 13. Cell Plate, L = 9. Unreplicated Chromosomes)

Step3: Identify cell types

Top diagram: Animal cell (has centrosomes, uses contractile ring for cytokinesis, rounded cell shape)
Bottom diagram: Plant cell (has rigid square shape, uses cell plate for cytokinesis, no visible centrosomes)

Step4: Final matching list

1. Interphase: C
2. Prophase: D
3. Prometaphase: (no box label, part of D transition)
4. Metaphase: E
5. Anaphase: A
6. Telophase: B
7. Centrosomes: P (top), M (bottom)
8. Replicated Chromosomes: J
9. Unreplicated Chromosomes: L
10. Nuclear Envelope: I
11. Nucleolus: G
12. Contractile Ring: O
13. Cell Plate: N
14. Spindle: K
15. Unreplicated Chromatin: (not explicitly labeled, pre-interphase)
16. Replicated Chromatin: H

Answer:

Matching Answers:

1. C

3. (No boxed phase label; component part of D)
4. E
5. A
6. B
7. P, M
8. J
9. L
10. I
11. G
12. O
13. N
14. K
15. (Not explicitly labeled)
16. H

Cell Type Identification:

• Top diagram: Animal cell mitosis. This is confirmed by the rounded cell shape, presence of distinct centrosomes, and use of a contractile ring (structure O) to pinch the cell into two during cytokinesis.
• Bottom diagram: Plant cell mitosis. This is confirmed by the rigid, square cell shape (due to a cell wall) and use of a cell plate (structure N) to form a new cell wall between daughter cells during cytokinesis, instead of a contractile ring.
