Mitosis Foldable

Do Now

• On a whiteboard, put the following events in order based on your knowledge of cell division (mitosis)

– A) Spindle fibers attach to the chromatids at the centromere; chromosomes appear at the equator of the cell

– B) Two new nuclei form and chromosomes unwind into chromatin

– C) Centrioles and spindle fibers appear and begin to move to the poles; chromatin condenses into chromosomes

(easier to move around the cell)

– D) Chromatids separate and begin to move to opposite ends of the cell (poles)

Foldable

• Step 1

– Fold your paper in half length wise (hot dog)

• Step 2

– Fold your paper in half twice from top to bottom

(create quarters)

• Step 3

– Unfold and cut each quarter through the front panel only (see Mr. Tran’s example for help)

Foldable

• Step 4

– On each front flap, list the 4 phases of mitosis

• Prophase, Metaphase, Anaphase, Telophase (PMAT)

• Step 5

– On the inside of each flap, list the key events/steps that occur in that phase (check notes/videos)

• Ex. Prophase- Mitosis begins, centrioles and spindle fibers appear and begin to move to opposite sides of the cell, chromatin condenses into chromosomes

• Step 6

– On the opposite side, draw a picture of a cell in that phase

(be sure to label the structures listed on the whiteboard)

Looking ahead

• Tomorrow

– Mitosis review

• Friday

– Mitosis Quiz

• Mitosis flip books may be edited based on today’s activity and help from Mr. Tran and turned in by Friday (before quiz)
