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

Asexual Reproduction
• A new organism is produced from one
organism.
• Reproduce by fission-an organism that
does not have a nucleus copies its genetic
material and divides into two identical
organisms.
