1. 10/30/14
Bell work:
What are the phases
and stages of the cell
cycle?
#8
Objectives:
Students will graph data.
Students will identify the
phases of cell cycle.
Students will explain
how a cell divides.
Announcements:
• FINISH SCIENCE FAIR EXPERIMENT!!!
• Tables & Graphs due Mon. 11/3

2. Instead of taking notes,
check your worksheet.
(ADV: check your notes)
Ch. 3.1 Cell Cycle & Cell Division

3. Focus Questions:
1. What are the phases of cell cycle?
2. What happens to the DNA during the cell
cycle?
3. What happens during the mitotic phase?
4. Why is cell division important?

4. 1. What are the phases of cell cycle?

5. During which part of cell cycle does a
cell spend most of its life?
A. Mitosis
B. Interphase
C. Prophase
D. Metaphase
E. Telophase
F. Anaphase
G. Cytokinesis

6. 1. What are the phases of cell cycle?
Cell cycle
Interphase
(growth &
development)
G1 stage:
Rapid growth (some
cells stop here)
S stage:
growth & DNA
copied
G2 stage:
growth & storing
energy for division
Mitotic phase
(cell division)
Mitosis:
Division of nucleus
Cytokinesis:
division of
cytoplasm
Organelles replicate
Check the “Phases of
the cell cycle chart”

9. 2. What happens to the DNA during the cell
cycle?
Copy on the back
1. Interphase – DNA is
copied during S stage
2. DNA coils up into
chromosomes
3. Identical
chromosomes pair up
to form a duplicated
chromosome (with 2
sister chromatids)

10. 2. What happens to the DNA during the cell
cycle?
Copy on the back
4. During mitotic phase,
sister chromatids will
divide into 2 cells
Draw this

11. What is the name for the coiled up
DNA that are an X-shape?
A. Chromatid
B. DNA
C. Chromatin
D. Chromosome

12. 3. What happens during the mitotic phase?
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
Mitosis
(nucleus &
DNA divides)
Cytoplasm & rest
of cell divides

18. Which of the following is NOT a part of
mitosis?

19. 4. Why is cell division important?
• Reproduction – unicellular organisms
• Growth & development
• Replacement – replaces old & worn out cells
• Repair – from injuries & other damage
