Data Collection Today Group A will collect data from Four untreated control onions Next week Group B will collect data from Four untreated control onions These will comprise. Cytokinesis. 01-08-09. http://www.cellsalive.com/mitosis.htm. Cell Division. The division of eukaryotic cells occurs in two main stages. Mitosis is the first stage. Is the process by which the nucleus of the cell is divided into two nuclei, each with the same number and kinds of chromosomes as the parent cell. Be sure to turn in any labs from yesterday. . . Today . we will be discussing:. Mitosis. Every minute your body needs to make 300 MILLION new cells!!. Your DNA carries all the instructions for the cell, including when to do mitosis.
