Worksheet: Stem Cells

In this worksheet, we will practice recalling the location and function of stem cells, and explaining how they can be used in medicine.

Q1:

Where are stem cells found in plants?

  • ARoot hair cells
  • BPalisade cells
  • CPollen
  • DMeristem
  • EChloroplasts

Q2:

True or False: Stem cells could be used to treat a range of disorders and diseases, including paralysis, dementia, and infertility.

  • ATrue
  • BFalse

Q3:

What is the key difference between a stem cell and a normal body cell?

  • ANormal body cells contain genetic material, whereas stem cells do not.
  • BStem cells can divide and replicate, whereas normal body cells cannot.
  • CStem cells are only found in embryos, whereas normal body cells are only found in adults.
  • DNormal body cells are specialized to carry out a particular function, whereas stem cells are unspecialized.
  • EStem cells are specialized to carry out a particular function, whereas normal body cells are unspecialized.

Q4:

Macular degeneration is when the light-sensitive cells in the center of your eye stop working. Which of the following best explains how stem cells could be used to treat someone with macular degeneration?

  • AStem cells cannot be used to treat this condition.
  • BStem cells can be used to create an entire eyeball and replace the eye of someone with this condition.
  • CStem cells can stimulate the immune response to repair the damaged cells.
  • DStem cells can be stimulated to differentiate into light-sensitive cells to replace the damaged ones.
  • EStem cells can be inserted into the eye to fix the damaged cells.

Q5:

Which of the following is a benefit of having stem cells in the body of a human adult?

  • AIf cells are damaged by injury or disease, stem cells can divide and create new cells to replace them.
  • BAdult stem cells can specialize into all the different types of cells in the body.
  • CAdult stem cells contain large amounts of hemoglobin to carry oxygen around the body.
  • DAdult stem cells can transmit electrical impulses to allow a rapid response to danger.
  • EAdult stem cells can be used in reproduction.

Q6:

Which of the following is the correct definition of stem cells?

  • AStem cells are undifferentiated cells that stay unspecialized.
  • BStem cells are undifferentiated cells that can develop into any type of specialized cell.
  • CStem cells are specialized cells found in the body that carry out certain functions.
  • DStem cells are undifferentiated cells that are only found in adult tissue.
  • EStem cells are undifferentiated cells found only in plants.

Q7:

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

  • AAdult stem cells can differentiate to become any type of specialized cell, but embryonic stem cells can only become certain types of cells.
  • BEmbryonic stem cells can differentiate to become any type of specialized cell, but adult stem cells can only become certain types of cells.
  • CThey do not differ in any of their properties.
  • DEmbryonic stem cells can divide rapidly to make new cells, but adult stem cells take a long time to divide and generate new cells.
  • EAdult stem cells can divide rapidly to make new cells, but embryonic stem cells take a long time to divide and generate new cells.
