Question

label the phases of mitosis below: 11. 12. 13. 14. 15. complete the table by checking the correct column for each statement. statement interphase mitosis 16. cell growth occurs 17. nuclear division occurs 18. chromosomes are finishing moving into separate daughter cells. 19. chromosomes are duplicated 20. dna synthesis occurs 21. where cells spend most of their life 22. mitochondria and other organelles are made. use the following illustrations for questions 23 - 32 23. in cell a, what is the structure labeled x? __________ 24. in cell f, what is the structure labeled y? ________ 25. which cell is not in a phase of mitosis? ________ 26. new nuclear membranes are forming in b. what is this phase called? ________ 27. sequence the six diagrams in chronological order from first to last. , , , , , 28. chromosomes move to the middle of the cell during? ________ 29. when do the sister chromatids separate? ________ 30. during which phase do chromosomes first become visible? ________ 31. during which phase does the cleavage furrow start forming on animal cells? ________ 32. if a cell has 46 chromosomes, how many chromosomes will each daughter cell have after mitosis? __________

Explanation:

• 11 - 15: Mitosis has phases pro - phase, meta - phase, ana - phase, telo - phase and cytokinesis. Identify based on chromosome and nuclear membrane appearance.
• 16 - 22: Interphase is for cell growth and DNA synthesis. Mitosis is for nuclear division.
• 23 - 24: Identify cell structures based on their appearance and position in mitosis.
• 25: Interphase cells are not in mitosis.
• 26: New nuclear membranes form in telophase.
• 27: Order based on mitosis phase progression.
• 28 - 31: Match events to mitosis phases.
• 32: Mitosis results in daughter cells with same chromosome number as parent cell.
