1. Introduction-cell division
Cell division is the process by which a parent cell divides into two or more daughter cells. Cell arise only from preexisting cells. Cell division plays several important roles in the live of organism. Cell division on large scale allows some multicellular organism reproduce asexually (such as plants that grow from cuttings.) Among sexually reproducing organisms, cell division is the basic of sperm and egg formation. Cells are classified into two categories: simple, non-nucleated prokaryotic cells, and complex, nucleated eukaryotic cells.
- cell cycle The process of cell division is a key component of the cell cycle, an ordered sequence of events that estends from the time a cell is first formed from a dividing parent cell untill its own division into two cells. |
