Why is cell division important? The Cell Cycle Mitosis Asexual Reproduction
Why is cell division important? • Cell division increases the number of cells in an organism causing it to grow. • Cells continue to grow and replace worn out cells. • One-celled organisms reproduce by cell division.
The Cell Cycle • Length of cycle is different for all types of cells. • Interphase- cell grows and functions, organelles duplicate, DNA is copied, chromosomes duplicate, cell grows and prepare for mitosis.
Mitosis • It is the division of a nucleus. • It produces two new nuclei that are identical to each other and the original nucleus. • Each new nucleus has the same number and type of chromosomes. • Include the following steps – – – prophase metaphase anaphase telophase cytoplasm divides
