Cell division is the growth mechanism and means that organisms use to proliferate and regenerate. Mitosis is the process by which cells divide and it leads to the growth of two identical daughter cells. In all Eukaryotic cells mitosis follows the same stages and these are named interphase, prophase, metaphase, anaphase, and telophase.
Interphase is the phase that takes place immediately after the production of new daughter cells. During this phase, cells carry out much of their usual functions including growth and protein synthesis. In most tissues, cells spend the majority of their lives in interphase. A specific example is brain tissue where mature cells remain in interphase their entire lives.
