General+brief+definition+of+mitosis.

Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. __Samia El Kurdi:__ No, not all cells undergo mitosis. __Samia El Kurdi:__ The cells that do not undergo mitosis are the brain and blood cells. __Samia El Kurdi:__ Mitosis differs between plant and animal cells in the following aspects: centrioles are present in animals while they are not present in plants. In addition, plant cells divide by cell plates while animal cells divide by cytokinesis.
 * **__do all cells undergo mitosis?__**
 * __kawssar:__ no not all cells.**
 * __Alia Olivia:__ No, some undergo meiosis.**
 * **__what are the cells that donot undergo mitosis?__**
 * __kawssar:__nervous system cells that undergo mitosis during embryogenesis only**
 * __Alia Olivia:__ Brain and Blood cells do not undergo mitosis.**
 * **__how does mitosis differ between plant and animal cells?__**
 * __kawssar:__ it differs in two things: plant cells form cell plates while animal cells form cleavage furrow**
 * presence or absence of centrioles**
 * __Alia Olivia:__ Centrioles are in animals but not in plants (centrioles assist in creating the spindle)** **plants divide the cells in telophase by cell plate while plants divide by cytokinesis.**
