  1. Complete Mitosis.Review and Practice Mitosis

  2. Objective: • Students will review the key steps of mitosis prior to applying their knowledge on a practice mitosis quiz. Warm Up: • What are the results of mitosis? • What are the key steps of prophase and metaphase? • What is the difference between animals and plants doing cell division (specifically cytokinesis “cutting”)? • Mitosis is one cell dividing into 2 daughter cells

  3. Warm Up: • What are the key steps of prophase and metaphase? • Prophase: “prepare” • The chromosomes supercoil • The nuclear membrane dissolves • The centrioles move to the poles and send out spindle fibers that bind to either side of each chromosome’s centromere. • Metaphase “middle” • The spindle fibers pull with equal tension on each chromosome, causing them to all align in the middle or equator of the cell.

  4. Animals vs. Plants • Why can’t plants have a cleavage furrow? • Their cell walls are too rigid, so instead pinching apart a cell plate forms in between the two daughter cells.

  6. Observing Mitosis in Onion Root Tip Slides Stages of Mitosis Anaphase (onion) Telophase (onion)

  7. Chose between the following phases: Anaphase, Metaphase, Prophase, Telophase/Cytokensis, G1 Interphase, S Interphase 1. Chromosomes line up along the center of the cell. 2. The chromosomes replicate 3. The chromosomes supercoil and are now visible under a light microscope. 4. The chromosomes move toward opposite poles. 5. Centrioles move to the poles and create spindle fibers. 6.The nuclear membrane disassembles. 7. The nuclear membrane reassembles. 8. Spindle fibers attach to the chromosomes. 9. The cell splits into two cells. 10. The cell makes proteins and grows larger. 11. What is the difference between cytokenesis in an animal cell and in a plant cell.

  8. Now Let’s Look at DNA BCRs • Please somewhere on your paper reflect on the following questions: • Have I answered all parts of the question? • Have I explained and defended my answer with concepts I learned in class and examples from labs or activities? (“How Do You Know” Factor ) • NOTE: Underline the “How Do You Know” Factor in your answer • Reflection: How well are you writing scientifically? How will you improve? • Based on your answers, you may want to edit your BCR before its graded, please do so in a different colored pen or colored pencil before handing it in.
