are lined up in the middle of the cell?
_________________________
9.
In what mitosis stage are the chromatin tightened,
the sister chromatids are attached at the centromere, the spindle fibers form
in the cytoplasm, the nuclear envelope seems to disappear and spindle fibers
are attached to the sister chromatids?

resulting mass of cells divides repeatedly until there are about ____ to ____
cells.
EXTRA
CREDIT:
REVIEW
your Mitosis Worksheets and be able to label the stages of Mitosis
ALSO HERE IS INFORMATION FOR THE PROJECTS THAT ARE DUE December 12, 2011
Dakosha has Prophase
William has Metaphase
Lora has Anaphase
Sharon has Telophase
Shakita has Telophase
The Cell Project will be done on a standard paper available in the library or in many stores in town. The Cell project is an individual students work. Students should:
- Drawn to size on the poster board
- Colored with colored pencils or markers
- Label correctly
- Put your name in the lower left hand corner
THIS IS WORTH 200 Points
