The document summarizes the life cycle of a cell. It begins by asking if all cells are doing the same thing at the same time, then discusses the cell cycle. It states that cells spend most of their time in interphase, which has three parts: G1, synthesis, and G2. During synthesis, DNA is duplicated. It then discusses mitosis and the steps of prophase, metaphase, anaphase and telophase. During these phases, the cell duplicates its DNA, separates the chromosomes, and divides into two daughter cells.

1. The Life Cycle of a Cell
The Cell Cycle and Mitosis

2. Are all cells doing the same thing
at the same time?
Find examples of cells that look like they are doing something different.

3. The Cell Cycle
A cell spends most of it’s life in what part of the cell cycle?

4. Mitosis- making a new nucleus,
then a new cell

5. Steps of Mitosis

6. Chromatids
Cell Wall
Cytoplasm

7. Interphase

8. What phase is the cell shown in? Prophase
The original and duplicate strands
of DNA are called sister….
Chromatids
What disappears during prophase?
Nuclear membrane, nucleolus

9. What phase is the cell shown in? Metaphase
Where are the chromatids located
during metaphase? Middle
What’s another name for the center or
middle of the cell? Equator

10. What phase is the cell shown in? Anaphase
What attaches the chromatids to
the spindle fibers? Centromere

11. Cell plate
What phase is the cell shown in? Telophase
What reappears in this phase?
Nuclear membrane, nucleolus

12. How does cytokinesis differ in this cell from the
one shown in the previous slide?

13. What are the two organelles (circled in
red) that migrated to opposite poles of
the cell during prophase called? Centrioles
What role do these organelles play in cell
division? They form the spindle apparatus

14. What do we call the two cells formed from
mitosis?
Daughter cells

15. What are the three parts of G1 Synthesis
interphase called?
G2
What happens to the DNA
during the synthesis stage? Duplication

16. Why do we duplicate the DNA during
interphase?
So that the daughter cells have the
same information as the mother cell!
