definition: The nucleus is surrounded by nuclear envelope which has chromatin formed. There is a pair of centrioles in the cell. The spindle fibers also start to form.
prophase:
definition: Chromatin is coiled up. This impacts the chromosomes. The chromosomes are then shortened and get thicker. The spindle fibers have completely formed.
metaphase:
definition: The spindle fibers move towards the sides of the cell which cause the chromosomes to go to the middle of the cell.
anaphase:
definition: The chromatids of each chromosome separate to make 2 daughter chromosomes. The spindle fibers pull the chromosomes to opposite sides of the cell.
telophase/cytokinesis:
definition: The spindle fibers dissolve. Then the chromosomes uncoil. The nucleolus/ nuclear envelope are formed again. Then the cytoplasm is divided into 2. 2 new cells are made.
