Cell Differentiation and Stem Cells

Stem cells are

• cells that grow uncontrollably

• undifferentiated and can be any type of cell

• never go through cell division

• only found in embryos

Answer explanation

Stem cells are undifferentiated and can become any type of cell. They are not cells that grow uncontrollably, never go through cell division, or only found in embryos.

Stem cells can be obtained from

• embryos

• some adult tissues

• umbilical cord blood

• all of the above

Answer explanation

Stem cells can be obtained from embryos, some adult tissues, and umbilical cord blood. Therefore, the correct answer is '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

Answer explanation

Pluripotent means the ability to divide and produce various types of cells.

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. 

Answer explanation

Muscle cells and blood cells differ in gene activation.

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

Answer explanation

Embryonic stem cells have greater differentiation potential compared to adult 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.

Answer explanation

Embryonic stem cells have the ability to develop into any cell type in the body, making them highly versatile and valuable for medical research and potential therapies.

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

Answer explanation

Cell differentiation is the process by which cells become specialized, acquiring specific structures and functions.

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

Answer explanation

The goal of cellular differentiation is to create specialized cells that help maintain homeostasis in organisms.
