2  I can place in order pictures that show chromosome movement during cell division.  I can classify methods of reproduction as sexual or asexual.

3 How do little elephants grow up to be BIG elephants?

5  Single parent produces offspring that are identical to the parent  Organisms with eukaryotic cells reproduce by mitosis and cell division

6 1. Growth 2. Repair 3. Replacement

7  Budding – using mitosis and cell division to form a bud which will become a new organism  Regeneration – using mitosis and cell division to regrow body parts

8  Cell division occurs in a series of stages, or phases.

9 Cell Cycle http://www.cellsalive.com/mitosis.htm Interphase Prophase Metaphase Anaphase Telophase & Cytokinesis

10 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

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

12 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

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

14 Chromatids (or pairs of chromosomes) attach to the spindle fibers. Line up along the center of the cell Centrioles Spindle fibers

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

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

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

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

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

20 Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes. Same # as original Plants form a cell plate to divide cytoplasm
