Reproduction Review

1. What does this diagram represent?

2. Identify structures A and B.

3. During what phase of mitosis is this structure produced?

above? Mitosis

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.

Prophase

The nuclear membrane is disappearing.

Spindle fibers start to form.

Spindle fibers

Centrioles

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 Metaphase Anaphase

Telophase 2 daughter cells that are genetically identical tp parent cell.

1.What process is represented?

2.What type of cells are represented above?

CBA D E F

Mitosis

Plant cells because they are rectangular

3. If the first cell is made up of 32 chromosomes, how many chromosomes are found in the daughter cells?

CBA D E F

32

In mitosis, daughter cells have the same number of chromosomes as parent cell.

4. How is this different from animal cell mitosis?

CBA D E F

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.

Binary fission

Vegetative propagation

What are the differences between asexual and sexual reproduction?

•Asexual repro uses one parent while sexual repro uses 2 parents.

•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.

•Asexual repro uses mitosis while sexual repro uses meiosis.

What are the differences between mitosis and meiosis?

•Mitosis produces 2 daughter cells while meiosis produces 4 daughter cells.

•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).

•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.
