Describe the 2 daughter cells in stage F.
They have the same # of chromosomes as the parent cell.
They are genetically identical to the parent cell.
For each of the following pictures, identify the phase
of mitosis and what is occurring. The pictures are
out of order.
Anaphase
The double chromosomes
are pulling apart and
moving to opposite poles.
Centrioles
Spindle fibers
Prophase
The nuclear membrane is
disappearing.
Spindle fibers start to form.
Metaphase
Chromosomes are lined up
in the middle of the cell,
Interphase
Chromosomes replicate.
Looks like a normal cell.
Telophase
Nuclear membrane has
started to form around
each set of chromosomes
Cytokinesis has begun
(the cell membrane is
pinching in).
Interphase
Prophase
Telophase

Anaphase

genetically identical tp parent
cell.

3. If the first cell is made up of 32 chromosomes,
how many chromosomes are found in the
daughter cells? 32
In mitosis, daughter cells have the same
number of chromosomes as parent cell.
A
B
C
D
E
F
4. How is this different from animal cell
mitosis?
In plant cell mitosis, cytokinesis occurs as a result of the
cell plate forming between the 2 daughter cells.
In animal cell mitosis, cytokinesis occurs as a result of the
cell membrane pinching in between the 2 daughter cells.

1.What is the name of the process represented in
the diagram? Binary fission
2. What type of cell division is involved? mitosis
3. Identify some organisms that use this process.
ameba, paramecia, bacteria
4. What type is reproduction is represented?asexual
5. Describe the offspring of this process.
offspring genetically identical to parent cell.
1.What is the name of the process represented in
the diagram? Budding
2. What type of cell division is involved? mitosis
3. Identify some organisms that use this process.
Yeast, hydra
4. What type is reproduction is represented?asexual
5. Describe the offspring of this process.
offspring genetically identical to parent cell.
Identify each type of asexual reproduction below.

What are the differences between asexual
and sexual reproduction?
•Asexual repro uses one parent while sexual repro
uses 2 parents.
•Asexual repro uses mitosis while sexual repro uses
meiosis.
•Asexual repro produces offspring that are
genetically identical to the parent. Sexual repro
produces offspring that are similar but NOT
genetically identical to the parents.
•Sexual repro involves the joining of gametes while
asexual repro does not require gametes.
What are the differences between mitosis
and meiosis?
•Mitosis produces 2 daughter cells while meiosis
produces 4 daughter cells.
•Mitosis produces daughter cells with the same # of
chromosomes as the parent cell while meiosis
produces daughter cells with the half the # of
chromosomes as the parent cell.
•Mitosis is used for asexual reproduction while
meiosis is used for sexual reproduction.
•Mitosis is used to replicate somatic cells while
meiosis produces gametes (sex cells).
