Telophase

12

In sexually reproducing multicellular organisms, the main functions of mitosis are...

Tissue repair/replacement of damage cells ; growth and development

13

Which events occur during prophase?

Chromosomes condense and are attached to spindle fibers ; the nuclear envelope breaks down.

14

Cytokinesis ___

Finished mitosis by dividing the cytoplasm and organelles of the original parent cells into two separate daughters cells

15

During_____, the cell carries out its normal functions and the chromosomes are thinly spread out though out the nucleus.

Interphase

16

Looking through a light microscope at the dividing cell, you see two separate groups of chromosomes on opposite ends of the cell. New envelopes are taking shape around each group. The chromosomes then begin to disappear as the unwind. You are witnessing _______.

Telophase
