4. 4. For each of the following pictures, identify the phase of mitosis and what is occurring. The pictures are out of order. A.
Anaphase
The chromosomes are pulling apart and moving to opposite poles.

5. B. Prophase The nuclear membrane is disappearing.
Centrioles
Spindle fibers
Prophase
The nuclear membrane is disappearing.
Spindle fibers start to form.

6. C.
Metaphase
Chromosomes are lined up in the middle of the cell,

7. D.
Telophase
Nuclear membrane has started to form around each set of chromosomes
Cytokinesis has begun (the cell membrane is pinching in).

d. How is this different from animal cell mitosis?
e. Label each step of mitosis above.
Mitosis
Plant cells 32
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.

Regeneration
Vegetative propagation
Vegetative propagation
Sporulation

17. 22. 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 (genetic variation).
Sexual repro involves the joining of gametes while asexual repro does not require gametes.
