Repair
What is this describing?
*Allows multicellular organisms, such as humans to grow and develop from one cell (a fertilized egg)
*Example: Human – cell division begins about 24 hours after fertilization and continues rapidly during the first few years of life
Reproduction
Growth
Replacement
Repair
What is this describing?
*Cell division is also critical for repairing damage

What is this describing?
*Even after an organism is fully grown, cell division continues.
*Replaces cells that wear out or are damaged
*Not all damaged can be repaired, however, because not all cells continue to divide
*Recall that mature nerve cells stop the cell cycle in interphase
*Example: Outermost layer of your skin is always rubbing or flaking off. A layer of cells below the skins’ surface is constantly dividing. Produces millions of new cells daily to replace the ones that are rubbed off.
*Example: Injuries to nerve cells often cause permanent damage
