Cell Differentiation

The process by which cells become more specialized in order to perform different functions is called:

• cell transformation

• cell differentiation

• stem cell changeability

• MAGIC!

Which of the following are specialized cells found in the human body? (select all that apply)

• lung cells

• pancreas cells

• heart muscle cells

• nuerons

• finger nail cells

Is this a true or false statement" All cells contain the same DNA, but each cell can be vastly different."

• True

• False

When does differentiation occur?

• when a stem cells turns into a specific type of cell

• when a stem cells leave G1 phase

• when cells enter mitosis

What determines what type of cell a stem cell will become?

• when certain genes in the cell get turned on or turned off

• only when all the genes in the cell get turned on

• only when all the genes in the cell get turned off

What is a stem cell?

• cells that can transform or become more specific and specialized

• cells that never stop working

• cells that never stop growing and dividing

• cells that are only present at birth

Do all cells in the human body start off as stem cells?

• Yes

• No

As we grow and develop, stem cells can become other cells, such as a heart cell or a liver cell, true or false?

• True

• False

Does a liver cell have the same DNA as a red blood cell?

• yes

• no

What is gene expression?

• how each cell express (turns on or off) their genes differently

• how each cell turns on their genes differently

• how each cell turns off their genes differently

• how each cell starts off very different from other cells
