Sexual reproduction involves how many parents?
Two

List the four phases of Mitosis in the correct order
Prophase
Metaphase
Anaphase
Telophase

On a solid surface, cells will grow and divide until they start to _____________.
Touch
100
Stem cells are the ______________ cells from which differentiated cells develop.
Unspecialized
100
What Phase of the cell cycle do cells spend 90% of the time in?
Interphase
200
What type of reproduction results in the offspring being a clone of the parent?
Asexual Reproduction
200
The three reasons multicellular organism depend on cell division
-Growth
-Repair
-Development
200
What is Apoptosis?
programmed cell death
200
During the development of an organism, cells differentiate to become
Specialized
200
What is the G0 phase
The non-dividing phase
300
Is it better for a cell to have greater surface area or volume?
Surface Area (This would mean the cell is small)
300
What is the DNA called in this picture
Chromatin
300
List the two proteins that help regulate the cell cycle
Growth factors and cyclins
300
What are totipotent stem cells?
Stem cells that can becomes any type of body cell
300
Explain what happens to a cell when it experiences Apoptosis.
The cell and its DNA will shrink, and then parts of the cell membrane breaks off. Neighboring cells then quickly clean up the cell’s remains.

Advantages for Asexual and Sexual Reproduction
Asexual: -Produce many offspring in short period
-Don’t need to find a mate
-In stable environments, genetically identical offspring thrive.
Sexual: -In changing environments, genetic diversity can be beneficial.

Explain the difference of Cytokinesis in Plant and Animal Cells
Plant cell: Have vesicles that form into a cell plate and then a cell wall.
Animal cell: Form a cleavage furrow and divided into two cells.

What is cancer? What are possible treatments?
Cancer: Uncontrollable growth of cells.
Treatments:
•Surgery to remove localized tumor
• Radiation to destroy cancer cell DNA
• Chemotherapy to kill cancer cells or slow their growth
400
What are Multipotent Stem Cells?
Cells that are limited to what they can become. They can only replace the tissue/cell they came from.
400
What phase of Mitosis involves the separation of the sister chromatids?
Anaphase
500
The formulas for
Surface Area of a Cube:
Volume of a Cube:
Surface Area: Length X Width X # of side (6)
Volume: Length X Width X Height
500
The Process by which Prokaryotic Cells Divide
Binary Fission
500
How many checkpoints does the cell cycle have? Where are each of them located?
There are three checkpoints:
(1st) G1 Checkpoint: Toward the end of G1
(2nd) G2 Checkpoint: At the end of G2
(3rd) M Checkpoint: In Metaphase of Mitosis
500
Why is Adult Stem Cell Research more accepted than Embryonic Stem Cell Research?
You may ask adults for their stem cell (permission) but you can not ask an embryo. Also, it would be taking the life of the embryo.

What phase of Mitosis are the centrioles 1st at complete opposite poles of the cell?
Metaphase
