Aim # 50: What are the stages of Mitosis?
HW:
Daily Review of Class Notes
Finish Practice Worksheet
All Labs due Friday
Do Now:
When do cells divide?
What must happen to DNA BEFORE cell division occurs?
3) Draw a duplicated chromosome and label the sister chromatids and the centromere.

2. Aim #50: What are the stages of mitosis?
Biology is the only subject in which multiplication is the same thing as division…

3. 1) What is mitosis? Spindle Fibers Chromosomes
Mitosis is the process that divides the cell’s nucleus into two,
each with a complete set of genetic material from the parent cell.

4. 2) What is interphase?
Phase of cell cycle in which a typical cell spends most of its life
in between cell divisions
Centriole

5. 3) What is going on within the cell during interphase?
Cell grows
DNA (chromosomes) replicate
Cell prepares to divide
Cell

6. 4) What is the Mitotic (M) Phase
M Phase- the cells undergo cell
division.
What does the “M” stands for?
Mitosis
The dance of the
Chromosomes

7. Stages of Mitosis (PMAT):
Prophase:
The chromosomes become
visible. (Condensation)
The centrioles separate and
Spindle fibers begin to form.
The nuclear membrane breaks
down.
Centriole
Nuclear
Membrane
Spindle Fibers

8. Stages of Mitosis (PMAT):
Metaphase:
The chromosomes line up across the center (Middle) of the cell.
Each chromosome is connected to
a spindle fiber at the centromere.

9. Stages of Mitosis (PMAT):
Anaphase:
The spindle fibers separate
the chromatids into individual
chromosomes and they
are moved apart.

10. Stages of Mitosis (PMAT):
Telophase:
The chromosomes gather at opposite
ends of the cell.
2) Two new nuclear membranes form.
The chromosomes lose their distinct
shapes.

11. 6) What is cytokinesis? The cytoplasm pinches and two cells
are formed.

12. What is the end result of Mitosis?
46X
46X
46X +
Parent
Daughter Cell
Daughter Cell
Is the genetic material of the
daughter cells identical to the
parent?
Chromosome Number?
The same number of
chromosomes is maintained
from one generation to the
next.
YES

13. 8) What is the difference between plant and animal cell division?
In plants, a Cell Plate forms across the middle of the cell.

14. Comparing animal and plant Cytokinesis
