ANALYZE (break apart, study the pieces) There is a question within a question in this DSQ. Can you identify the question within the DSQ?

10. Bell Work – 3/14/13 How do little elephants grow up to be BIG elephants?

12. The process of asexual reproduction begins after a sperm fertilizes an egg.

13. Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun. Cell that reproduce by asexual reproduction reproduce constantly.

14. Animated Mitosis Cycle http://www.cellsalive.com/mitosis.htm Cellular Reproduction occurs in a series of stages, or phases: Interphase Prophase Metaphase Anaphase Telophase & Cytokinesis

15. Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils ( chromatin ) at the start, but each chromosome and its copy( sister chromosome) change to sister chromatids at end of this phase CELL MEMBRANE Nucleus Cytoplasm

17. Mitosis begins (cell begins to divide) Centrioles (or poles) appear and begin to move to opposite end of the cell. Spindle fibers form between the poles. Centrioles Sister chromatids Spindle fibers

18. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm Spindle fibers

19. Chromatids (or pairs of chromosomes) attach to the spindle fibers. Centrioles Spindle fibers

21. Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers

23. Two new nuclei form. Chromosomes appear as chromatin (threads rather than rods). Mitosis ends. Nuclei Chromatin

25. Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes.
