B3 Retrieval Questions

1. 1What is a stem cell?

   1. Adifferentiated cell that can change into one or more specialised cell types
   2. Bundifferentiated cell that can differentiate into one or more specialised cell types
   3. Cundifferentiated cell that cannot differentiate into any other specialised cell types
2. 2What are adult stem cells?

   1. Astem cells from adults that can differentiate into any specialised cells
   2. Bcells from adults that cannot differentiate
   3. Cstem cells from adults that can only differentiate into certain specialised cells
3. 3Where are adult stem cells found?

   1. Abone marrow
   2. Bumbilical cord
   3. Cear lobes
4. 4What are embryonic stem cells?

   1. Astem cells from embryos that can differentiate into limited specialised cells
   2. Bstem cells from embryos that can differentiate into any specialised cell
   3. Cstem cells from embryos that are already specialised
5. 5Where are embryonic stem cells found?

   1. Aearly human embryos (usually from spare embryos from fertility clinics)
   2. Bbone marrow
   3. Cear lobes
6. 6In therapeutic cloning patient’s cells are used to create an early embryo [blank_start]clone[blank_end] of themselves – stem cells from the embryo can then be used to treat the patient’s medical conditions.

   1. Aclone
7. 7An advantage of therapeutic cloning is that stem cells from the embryo are not rejected when transplanted because they have the same genes as the patient

   1. ATrue
   2. BFalse
8. 8An advantage of using adult stem cells is that there are fewer ethical issues as obtained from adults who can consent to their use

   1. ATrue
   2. BFalse
9. 9Give a disadvantages of using adult stem cells.

   1. Aembryos must be destroyed
   2. Bcan only differentiate into some specialised cell types, so treat fewer diseases
   3. Ccan only differentiate into liver cells
10. 10Give two advantages of using embryonic stem cells.

    1. Acan differentiate into any specialised cell, so can be used to treat many diseases
    2. Beasier to obtain as they are found in spare embryos from fertility clinics
    3. Cdonors can be found easily
    4. Dliver cells can be produced

11. 11Two disadvantages of using embryonic stem cells are [blank_start]ethical[blank_end] issues surrounding their use, as every embryo is a potential life and potential risks involved with treatments, such as transfer of [blank_start]viral[blank_end] infections

    1. Aethical
    2. Bviral
12. 12What are plant meristems?

    1. Aarea where slowest cell division occurs in the tips of roots and shoots
    2. Barea where rapid cell division occurs in the tips of roots and shoots
    3. Carea where rapid cell division occurs in the middle of roots and shoots
13. 13Two advantages of using plant meristems to [blank_start]clone[blank_end] plants are that rare species can be cloned to protect them from [blank_start]extinction[blank_end] and plants with special features (e.g., disease resistance) can be cloned to produce many copies

    1. Aclone
    2. Bextinction
14. 14An advantage of plant cloning is that no genetic variation is introduced, so, for example, an entire cloned crop could be destroyed by a disease

    1. ATrue
    2. BFalse
15. 15What is cell division by mitosis?

    1. Abody cells divide to form two identical daughter cells
    2. Bbody cells divide to form four identical daughter cells
    3. Csex cells divide to form two identical daughter cells
    4. Dsex cells divide to form four identical daughter cells
16. 16The purpose of mitosis is the growth and repair of cells, and asexual reproduction

    1. ATrue
    2. BFalse
17. 17What happens during the [blank_start]first[blank_end] stage of the cell cycle? • cell grows bigger
    • [blank_start]chromosomes[blank_end] duplicate • number of subcellular structures (e.g., ribosomes and mitochondria) increases

    1. Achromosomes
    2. Bfirst
18. 18During mitosis one set of chromosomes is pulled to each end of the cell and the nucleus divides

    1. ATrue
    2. BFalse
19. 19What happens during the third stage of the cell cycle?

    1. Athe cytoplasm and cell membrane divide, forming four identical daughter cells
    2. Bthe cytoplasm and cell membrane divide, forming two different daughter cells
    3. Cthe cytoplasm and cell membrane divide, forming two identical daughter cells
    4. Dthe cytoplasm and nucleus divide, forming two identical daughter cells
