Total questions: 12
Worksheet time: 16mins
Stem cells are
cells that grow uncontrollably
undifferentiated and can be any type of cell
never go through cell division
only found in embryos
Stem cells can be obtained from
embryos
some adult tissues
umbilical cord blood
all of the above
What does "pluripotent" mean?
able to divide and make many different types of cells
not able to divide
can only divide and make one cell type
if it divides, it will make a cancerous tumor
What does "pluripotent" mean?

Which best explains why muscle cells are different from blood cells?
Muscle cells are produced by the brain, but blood cells are produced by the heart.
Different genes are activated in muscle cells than in blood cells.
Muscles cells experience different environmental influences than blood cells.
A mutation occurs during the development of muscle cells but not in blood cells.
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 are pluripotent, just like embryonic stem cells
Adult stem cells can differentiate into more cell types than embryonic stem cells
Adult stem cells grow bigger than embryonic stem cells
Which is true about embryonic stem cells?
They no longer divide, their cell type is set and cannot change.
They can develop into only one type of cell.
They can become any cell type in the body.
They are found in adults.
What is cell differentiation?
Process by which cells produce more cells
Process by which cells become specialized
Process by which cells become unspecialized
Process by which cells die
What is one goal of cellular differentiation/specialization?
To create specialized cells to help organism maintain homeostasis.
To many cells.
To make stem cells
to make single celled organisms
Stem cells are
cells that grow uncontrollably
undifferentiated and can be any type of cell
never go through cell division
only found in embryos
Stem cell research is controversial because in involves?
social issues
ethical issues
educational issues
economical issues
What is the importance of apoptosis?
To eliminate damaged or unnecessary cells
To create specialized cells
To produce two identical cells
To cause uncontrolled cell growth
