What is Mitosis?
Cell and Nuclear division where 2 daughter cells/nuclei and produced and have the SAME number of CHROMOSOMES as the parent cell and each other - IDENTICAL
1 of 8
What are the 5 stages in order?
Interphase, Prophase, Metaphase, Anaphase, Telophase - I P M A T
2 of 8
What happens in the Interphase stage?
Longest Stage. Chromosomes invisible, Nucleolus, Nucleus envelope visible. Cell is actively synthesising proteins. Proir to mitosis, DNA replicates
3 of 8
What happens in the Prophase stage?
Chromosomes visible with 2 CHROMATIDS. Nuclear envelope disintergrates and Nucleous disappears
4 of 8
What happens in the Metaphase stage?
Spindle fibres form. Chromosomes line up in the MIDDLE (M) or centre of the cell
5 of 8
What happens in the Anaphase stage?
Spindle fibres attached to chromatids pull them APART (A). Pulled towards opposite poles or sides of the cell
6 of 8
What happens in the Telophase stage?
Chromatids reach sides and become indistinct. Neclear envelope and nucleous reforms. Spindle disintergrates. 2 identical cells - TWINS (T)
7 of 8
What is the 3 main reasons for mitosis?
GROWTH: Diploid cell from 2 haploid cells, has all genetic info to pass on, daughter must be identical. DIFFERENTIATION - Cells specify to perform a job so all cells must be identical to do that. REPAIR: new identical cells replace dead ones
