Mitosis review

Question/Answer review of the stages of the cell cycle and mitosis!

1. Warm Up!!! What phases of Mitosis did you see in the slides on Thursday??

2. Chapter 10 Cell division Review

3. This spot that holds the 2 chromatid copies together is called a ______________________ centromere

4. Cell division in bacteria cells is called _______________________ Binary fission Phase of the cell cycle in which DNA is copied S (synthesis)

5. Phase of the cell cycle in which the nuclear membrane is present and DNA is spread out into chromatin. interphase

6. Type of cell division in eukaryotic cells that results in 2 identical daughter cells. mitosis List the phases of mitosis in order starting with prophase. Prophase, metaphase, anaphase, telophase, cytokinesis

7. Phase of mitosis that follows anaphase telophase Phase of the cell cycle that follows G 2 Mitosis (prophase)

8. This network of fibers that attach and pull the chromosomes apart is called the mitotic ______________ spindle This cell is in __________________ prophase

9. G 1 , S, and G 2 make up this phase of the cell cycle. interphase

10. The place in the cell membrane of an animal cell that pinches in during cytokinesis is called a ____________________ cleavage furrow Plant cells can’t pinch to divide, instead they form a _______________ to divide. cell plate

11. This phase of the cell cycle is ______________ anaphase Part of interphase in which the cell grows to mature size and carries out its job . G 1

12. Phase of mitosis that follows prophase metaphase Phase of the cell cycle that follows S G 2

13. This phase of the cell cycle is ________________ metaphase Phase of the cell cycle cell’s spend most of their time in. G 1 of interphase

14. Phase of mitosis in which the nuclear membrane and nucleolus disappear and the DNA scrunches into chromosomes. prophase In this part of interphase cells make the molecules and organelles needed for cell division G 2

15. These structures at the poles which attach to the spindle fibers and pull the chromosomes. centrioles The cell above is in __________. metaphase

16. Phase of mitosis that follows metaphase anaphase Phase of the cell cycle that follows G 1 S

17. This cell is in ___________ anaphase Phase of cell division in which the nuclear membrane returns and chromosomes spread out into chromatin. telophase

18. This cell is in __________ telophase The cell above is a _________ cell. ( animal or plant) Plant You can see the cell plate forming in center instead of a cleavage furrow.

19. Phase of the cell cycle after S phase in which cells make the molecules and organelles needed for cell division G 2

20. Phase of mitosis in which chromatids separate and move to opposite ends of the cell. anaphase The very first dividing phase is _______________ prophase

21. Phase of the cell cycle where cells spend most of their time. They grow bigger and they do their job as body cells. G 1 List the phases of mitosis in order starting with interphase Interphase, prophase, metaphase, anaphase, telophase, cytokinesis

22. This is called a ______________ Cleavage furrow This cell is _____________ cell. (animal or plant) an animal Plants don’t have cleavage furrows.

23. Phase of mitosis where the cytoplasm splits into 2. Cytokinesis Name the phases of the cell cycle in order starting with G 1 G 1 S G 2 M C

24. ________________ DNA is all spread out as chromatin and nuclear membrane is visible ________________ DNA scrunches up and chromosomes are first visible ________________ Made up of G1, S, G2 ________________ Chromosomes line up in middle of cell INTERPHASE PROPHASE INTERPHASE METAPHASE Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I)

25. _______________ DNA is copied and cell prepares to divide _______________ Chromatid arms separate and move to opposite ends of the cell _______________ Chromosomes unwind into chromatin & nucleus returns _______________ Nuclear membrane & nucleolus disappear INTERPHASE ANAPHASE TELOPHASE PROPHASE Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I)

26. __________________ Two nuclei are visible __________________ First dividing phase ___________________ Centrosomes containing centrioles & spindle fibers appear next to nucleus __________________Cytoplasm is split between two cells _________________ Spindle fibers and centrioles disappear TELOPHASE PROPHASE PROPHASE CYTOKINESIS TELOPHASE Prophase (P) Metaphase (M) Anaphase (A) Telophase (T) Interphase (I)

27. _______ Cell is reading the DNA code and “doing its job” _______ Cell makes a copy of its DNA _______ Cells leave the cell cycle and stop dividing _______ Division of chromosomes happens G 1 S G S G 1 G 2 G Mitosis (M) Cytokinesis (C) M

28. _______ Division of cytoplasm happens _______ Cell makes the molecules and organelles needed for cell division _______ Made up of telophase, anaphase, prophase, and metaphase C G 2 S G 1 G 2 G Mitosis (M) Cytokinesis (C) M

29. THE END
