A B E C D F 5. Describe the 2 daughter cells in stage F. They have the same # of chromosomes as the parent cell. They are genetically identical to the parent cell.
6. For each of the following pictures, identify the phase of mitosis and what is occurring. The pictures are out of order. Anaphase The chromosomes are pulling apart and moving to opposite poles.
Centrioles Spindle fibers Prophase The nuclear membrane is disappearing. Spindle fibers start to form.
Metaphase Chromosomes are lined up in the middle of the cell,
Interphase Chromosomes replicate. Looks like a normal cell.

A B C D E F 7. What process is represented? Mitosis 8. What type of cells are represented above? Plant cells because they are rectangular
9. Which type of cell division does this diagram represent? Explain your answer. • Mitosis, 2 new cells made 10. If organism A contains 8 chromosomes, how many chromosomes would the offspring contain? • 8
A B C D E F 11. If the first cell is made up of 32 chromosomes, how many chromosomes are found in the daughter cells? 32 In mitosis, daughter cells have the same number of chromosomes as parent cell.
