2. Interphase-Growth and Perpetration.
During this first stage, the cell grows in size while it creates
proteins and nutrients essential for survival.
3. 4. Interphase-Replication
During this stage, the cell has two sets of DNA
5. 6. Interphase continued growth and preperation
In this stage, the cell continues to grow and make proteins for the
daughter cells.
7. 8. 9. 10. Mitosis-early Prophase
During early prophase, the chromosomes that were created in the
replication stage coil up into the X shape, and become visible
under a microscope. The nucleolus disappears, and only the membrane
remains. Spindle fibres, tiny tube-like structures, begin to appear
as well as centrioles, organelles that organize the fibres.
11. 12. 13. 14. 15. 16. Mitosis- late prophase
In late Prophase, the spindle fibres finish forming and attach
their centromeres to the chromosomes. The nuclear membrane
disappears.
17. 18. Mitoses - Metaphase
In Metaphase, the spindle pull the chromosomes in to the center of
the cell.
19. 20. 21. Mitosis - Anaphase
In Anaphase, the spindle fibres shorten and pull the chromosomes
apart, allowing the sister chromatids to move to opposite
poles.
22. 23. 24. 25. 26. 27. 28. 29. 30. Mitosis - Telophase
In Telophase, the final stage of Mitosis, a complete set of
chromosomes have now moved to opposite ends of the two daughter
cells. The spindle fibres start to disappear while a nuclear
membrane forms around the chromosomes. A nucleolus also forms in
each newly formed nucleus, meaning the cell is ready to
divide.
31. 32. Cytokinesis
The final stage of the cell cycle, Cytokinesis, is when the cell
finally divides. The nuclei separate into two daughter cells. The
new cells are identical to the parent cells. In animals, the
membrane pinches together to form these daughter cells, while in
plants a plate forms to divide them.
