What is mitosis and what cells is it for? What Are the stages?
|
Mitosis is the dividing of animal and plant cells to make identical copies of each other. There Are 4 phases of mitosis: Prophase, Metaphase, Anaphase and telophase.
|
|
Prophase
|
The longest stage in mitosis. The chromosomes Are visible and the centrioles separate and go to the oppisite sides of the nucleus. And spindles form.
|
|
Metaphase
|
Only lasts a few minutes and the chromosomes line up in the middle of the cell and each one is connected to a spindle fiber at the centromere.
|
|
Anaphase
|
The centromeres of the joined chromosomes split, allowing the sister chromatids to be individual chromosomes. And they move apart.
|
|
Telophase
|
The chromosomes gather at the separate enda of the cell and lose distinct shapes. The 2 new nuclear envolopes form but is not complete.
|
|
Telokinesis
|
The physical process in which the cells cytoplasm pinches and splits into 2 separate daughter cells but in plant cells a cell plate forms instead of pinching apart. And each cell has an exact copy of the chromosomes.
