Amitosis

Amitosis is the simplest possible way a cell can divide, and it happens without the elaborate chromosome-condensation and spindle machinery that mitosis and meiosis rely on. In amitosis, the nucleus itself simply elongates, and a constriction develops somewhere along its length. This constriction gradually deepens until it splits the nucleus into two daughter nuclei — usually unequal in size, since there is no mechanism ensuring the split is even. The division of the cytoplasm follows the same way, producing two daughter cells. Because it is such a rudimentary process, amitosis is typically seen in unicellular organisms, in abnormal cells, in old/aged cell …
