Stem cell basics

Stem cells are

• cells that grow uncontrollably

• never go through cell division

• undifferentiated and can be any type of cell

• only found in embryos

Stem cells can be obtained from

• embryos

• umbilical cord

• some adult tissues

• all of the above

What does pluripotent mean?

• able to divide and make different types of cells

• can only divide and make one cell type

• not able to divide

• if it divides it can metasize into cancer

What process best explains how muscle cells and nerve cells can develop from the same fertilized egg?

• genetic engineering

• differentiation

• survival of the fittest

• selective breeding

What is the difference between embryonic stem cells and adult stem cells?

• embryonic stem cells can differentiate into more cell types than adult stem cells

• adult stem cells can differentiate into more cell types than embryonic stem cells.

• adult stem cells are pluripotent, just like embryonic stem cells.

• adult stem cells grow bigger than embryonic stem cells.

This type of cell sends messages througout the body in the form of electrical impulse.

• muscle cell

• nerve cell

• male gamete cell

• skin cell

This type of cell carries oxygen throughout the body.

• gametes

• white blood cells

• red blood cells

• bone marrow

Which statement is true about embryonic stem cells?

• They no longer divide , their cell type is set and cannot change.

• They can become any cell type in the human body.

• They can develop into only one type of cell.

• They are found in adults.

This image represents the process of

• embryo development

• fertilization

• bacteria growth

• morula development

Which type of cell is unspecialized?

• skin cell

• liver cell

• stem cell

• muscle cell
