A) The diagram below shows six cells in various phases of the cell cycle. Note the cells are not arranged in the order in which the cell

cycle occurs. Use the diagram to answer questions 111.

!!!!!!!! 1. "ells A # $ show an early and a late stage of the same phase of the cell cycle. %hat phase is it&

!!!!!!!! '. %hich cell is in metaphase&

!!!!!!!!(. %hich cell is in the first phase of phase *mitosis)&!!!!!!!!+. ,ist the diagrams in order from first to last in the cell cycle.

-. n cell A/ what structure is labeled 0&

. Are the cells depicted plant or animal cells& 2xplain your answer.

a) f it were the other type of cell what would be different in the diagrams&3. %hat is the longest phase of the cell cycle&

4. %hy is mitosis important&

5. 6redict what would happen if an individual had faulty spindle fibers.

17. 6redict what would happen if cyto8inesis was s8ipped.11. 9ow does interphase fit into this cell cycle organi:ation listed above&
