Cell Continuity -is the unbroken succession of cells since life evolved billion years ago. New cells can only be produced by cell division. New cells are needed for o reproduction, o formation of multicellular organisms, and o cell replacement. Cell Cycle There are three stages of the cell Cycle : 1. Interphase -The cell grows, proteins are made, the number of organelles increases, DNA replication. 2. Division of the Nucleus: Mitosis: two daughter nuclei, genetically identical the original nucleus, are fis: formaormed. Meiostion of four haploid genetically 3.
