Prophase

• During the prophase, centrosomes, the microtubule creation and organizational control centers, move toward the opposite ends of the cell. Chromosomes within a cell's nucleus become more coiled, causing them to be more dense, which means they can be observed under a microscope. The chromosomes have duplicates attached to them at the center, which are called sister chromatids. The nuclear envelope disappears at the end of this phase.
  
  

Metaphase

• During the metaphase, centrosomes are now at opposite ends of the cell. Chromosomes and sister chromatids are lined up in a space equidistant from the poles of the cell. Each chromatid and chromosome becomes attached to a kinetochore microtubule coming from the centrosome that they are facing.
  
  

Anaphase

• Chromosomes and sister chromatids separate. Sister chromatids are now called chromosomes, and each set moves toward a centrosome at opposite ends of the cell.
  
  

Telophase

• Chromasomes are assembled at opposite ends of the cell, and a new nuclear envelope forms around them as they start to uncoil.
  
  

Cytokinesis

• Cytokinesis is when the cell undergoing mitosis divides into two. While animal cells simply pull apart during this phase, plant cells divide by forming a wall between the two daughter cells. New cell wall material is brought to the center by a complex system of microtubules.
