GCSE Stem Cells

What is a stem cell?

• A plant cell

• A specialised cell

• A differentiated cell

• An undifferentiated cell with the potential to become a specialised cell

What are 'adult' stem cells?

• Stem cells that can only differentiate into one specific type of cell

• Stem cells that can differentiate into any type of cell

• Embryonic stem cells that have been allowed to grow

• Stem cells which have already differentiated

What type of cell division occurs in stem cells?

• Binary fission

• Mitosis

• Meiosis

• Fertilisation

What are embryonic stem cells?

• Stem cells from an early embryo that can differentiate into all cell types

• Cells from the shoot of a plant

• Stem cells from babies

• Stem cells which are not differentiated

True or False: Stem cells in plants are found in meristems.

• True

• False

How could stem cells be used to treat someone with Type 1 diabetes?

• Injecting them into the bloodstream

• Embryonic stem cells can be made to produce healthy pancreas cells to make enough insulin

• Taken in a tablet form

• Adult stem cells can be made to produce insulin

Which of these are disadvantages of using embryonic stem cells? (Choose 3)

• Procedure will be painful for the patient

• The embryo cannot give conset to the procedure

• Risk of viral transfer

• Will cause harm/ death to the embryo

Which of these are disadvantages of using adult stem cells (eg bone marrow)? (Choose 3)

• Patient cannot give consent

• Can only treat a few diseases

• Procedure can be painful

• Risk of infection from procedure

Which of these conditions can be treated with stem cells? (Choose 2)

• Migraine

• Diabetes

• High blood pressure

• Paralysis

Which of these are advantages of using embryonic stem cells? (Choose 3)

• Can treat many diseases as they can become any type of cell

• No ethical issues

• Painless

• Can create many embryos in a lab
