The Eukaryotic Cell Cycle and Cancer
1. Why is cell division important for both unicellular and multicellular organisms?
Cell division is the only way single- celled organisms can reproduce and multicellular organisms
need cell division to grow and replace all dead and damaged cells.
2. Why does cell division remain important to an adult organism even after it is fully developed?
It remains important to even adults because cells need to continue to be renewed throughout life.
Also, as adults get hurts their wounds need to heal though cell division
3. Cells divide, differentiate, or die. What is differentiation?
Differentiation is when cells stop dividing to specialize in structure and function
4. What is apoptosis? What is its purpose?
Apoptosis is when cells undergo a programmed cell death. It will eliminate all unnecessary cells
during development and remove any unhealthy/damaged cells.
5. What are cell cycle regulators?
Cell regulators are molecular signals that can either stimulate or halt cell division. They can
either tell cells to differentiate or initiate cell deaths.
6. What happens if cell cycle regulators don’t function properly?
An organism can end up with too few or too many cells. People can experience things like hair
loss, warts, tumors etc.
7. Cells go through periods of growth and division. Cell division occurs during Mitosis.The rest
of the cell cycle is called interphase, during which a cell grows and replicates its DNA.
8. Fill in the details about what happens during the three phases of interphase labeled in the
diagram
G1 Checkpoint- the cell increases in size and prepares to replicate its DNA.
