Cell Division- Mitosis
Cell Division- Mitosis As a cell grows, more demand is placed on exchange of materials (nutrients intake, waste removal intake). Also more demands are placed on its DNA As a cell grows it's surface area grows slower (Pie R Squared) than its volume (Pie R Cubed). When the ratio of Surface Area/Volume reaches a specific point chemicals called cyclins begin the cell division process.
What are chromosomes? They are a protein structure that contain …

…functions but does not reproduce.
Next comes the "S" phase. In this phase DNA is replicated and Chromosomes duplicated in Chromosome pairs. After this comes a short "G2" phase where molecules and organelles that cause Mitosis are produced. The last phase is "M" or Mitosis phase.
Mitosis has four steps: A. Prophase B. Metaphase C. Anaphase D. Telephase the cell seperates into two new cells. In animal cells it completely seperates, this is called cytokinesos.
