a process of cell division that forms two new nuclei, each of which has the same number of chromosomes

Cytokinesis What is the importance of Mitosis and Cytokinesis to the cell cycle?

First and longest phase of mitosis. The nuclear envelope dissolves (goes away), chromatin coils up and condenses to form visible chromosomes.

The short second phase of mitosis. The doubled chromosomes become attached to the spindle fibers at their centromeres and move to the equator of the cell.

The 3 rd phase of mitosis. During this phase, the centromeres split and the sister chromatids are pulled to opposite poles of the cell by the shortening of the microtubules.

The final phase of mitosis. Two distinct daughter cells are formed and the cells begin to separate. This stage is indicated by the formation of a cell plate in plant cells and a cleavage furrow in animal cells. Cell Plate Cleavage Furrow

Why is Cytokinesis important?

Mitosis guarantees genetic continuity. When mitosis is complete, unicellular organisms remain as single cells, In multicellular organisms cell reproduction results in cells that work together as tissues  tissues work together to form organs  organs to form organ systems  and organ systems form organisms.

In lab groups, go to your tables, open the envelope and look at the mitosis stages and description cards

Place the cards in the correct order of mitosis with description in the middle and the pictures of each stage on the outside.
