Cell Division

Cell Division

Multiple Choice

What type of cells are you made of?

• prokaryotic

• eukaryotic

• alien

You are Eukaryotic

All complex organisms are made of eukaryotic cells. These cells have a clearly defined nucleus and are capable of specializing to form tissues and organs.

Multiple Choice

Prokaryotic cells divide by this method:

• mitosis

• cytokinesis

• binary fission

• meiosis

Prokaryotes use binary fission

These simple, single-celled organisms just split when they get too large.

Multiple Choice

Which term is not a part of the Eukaryotic cell cycle?

• cytokinesis

• mitosis

• interphase

• fission

The cell cycle:

• Interphase: cell grows, replicates DNA, does it's job (about 90% of time)

• Mitosis: The nucleus divides (around 10% of time)

• Cytokinesis - rest of cell divides and membrane grows back

The term for regular body cells is somatic cells and the term for reproductive cells is gametes

Multiple Choice

All somatic cells contain____ DNA

• the same

• different

All somatic cells contain the SAME DNA

Multiple Choice

What's so important about stem cells?

• The are not differentiated, so they can become and replace other types of cells

• They are most prevalent in the embryonic phase

• They may be a used to cure certain diseases

• All of these answers

Yes, stem cells can do all those things!

Stem cells are undifferentiated cells. There are two types: embryonic and somatic stem cells. Embryonic (found in unborn babies) stem cells have a higher ability to differentiate, but stem cells can also be found in some somatic (body cells) especially bone marrow. Stem cells take cues from body sources and differentiate into other cells.

Multiple Choice

A mutation is...

• Always a bad thing

• An error in the cell cycle that results in a change in the DNA

• Always another name for cancer

• something that can be fixed with additional cell divisions.

A mutation is ....

• An error in the cell cycle that results in a change in the DNA

• mutations can be good, bad, or neutral

• mutations occur at a very small rate, but since your since your body has about 37 trillion cells, they happen in everybody

• mutations can occur randomly or because something interfered with the cell cycle - like radiation, temperature, or chemicals.

Multiple Choice

I get this chapter, it's easy peasy lemon squeezy...

• true

• False
