A.naphase
T.elophase - 2What is Mitosis?A parent cell that divides into two daughter cells- each an exact copy of the parent cell.
- 3What is Mitosis used for?To increase the number of cells for growth and repair
- 4—INTERPHASE
This isn't actually part of Mitosis.
The cell carries out normal function in preparation for Mitosis. The organelles within the cell replicate. - 5PROPHASE The chromosomes appear and the nuclear envelope disappears.METAPHASE
The chromosomes line up along the equator of the cell. Spindle fibres attach themselves to the centromere of the chromatid - 6ANAPHASE The centromeres divide as spindle fibres pull cromatids to separate sides of the cell.TELOPHASE
Cytokenisis occurs, this is where the cytoplasm divides in half forming the two daughter cells. the cell them returns back to interphase.
