Aim #48: How can we compare
animal and plant cell mitosis?
Mitosis Review
What are the stages of Mitosis?
Interphase
Prophase
Metaphase
Cytokinesis
Anaphase
Telophase
Mitosis Review
Place the following events of mitosis in the
correct order.
a.sister chromatids align along the metaphase
plate
b.the cell begins to cleave
c.the nuclear membrane breaks up
d.DNA begins to condense
e.sister chromatids separate
dcaeb
What is Interphase?
How do we know the cell
is in Interphase?
The part of the cell cycle
that includes:
G1, S, and G2 phase.
1) The chromosomes are
not visible.
2) The nuclear membrane is
intact.
Plant Cells vs. Animal Cells
Which are plant cells and which are animal cells?
Animal Cells
Cell Wall
Plant Cells
Plant Cell Mitosis
What phase is this?
Interphase
How do you know?
1) Nuclear membrane is
visible
2) Chromosomes aren’t
visible
Nucleus
Which cells are going through mitosis?
Plant Cell Mitosis
What Phase is this?
Prophase
How do you know?
1) Chromosomes become
visible
2) Nuclear membrane is
disappearing
3) Spindle Fibers begin to
form
Plant Cell Mitosis
What Phase is this?
Metaphase
How do you know?
1) Chromosomes line up
along center of the cell
2) Each chromosome is
connected to a spindle
fiber at the centromere
Plant Cell Mitosis
What phase is this?
Anaphase
How do you know?
1) The spindle fibers separate
the chromatids into individual
chromosomes and they are
moved apart.
Plant Cell Mitosis
What phase is this?
Telophase
How do you know?
1) The chromosomes gather
at opposite ends of the cell.
2) Two new nuclear membranes form.
3) The chromosomes lose their distinct
shapes.
Plant Cell vs. Animal Cell Mitosis
How is plant cytokinesis different
than animal cell cytokinesis?
In an animal cell, the
cytoplasm pinches off.
What process is this?
Cytokinesis
In plants, a Cell Plate forms
across the middle of the
cell.
Plant Cell vs. Animal Cell Mitosis
Animal Cell
Centrioles
Plant Cell
Plant cells have no
centrioles
