  • Q1
    What is a stem cell?
    a plant cell that helps the plant stem grow
    undifferentiated cell that can differentiate into one or more specialised cell types
    a specialised cell that can differentiate into one or more specialised cell types
    undifferentiated cell that can grow into a more specialised cell
    60s
  • Q2
    What are adult stem cells?
    stem cells from embryos that can differentiate into any specialised cell
    what stem cells become when they differentiate
    stem cells from adults that can only differentiate into certain specialised cells
    stem cells that are much older and are able to differentiate into many more cell types
    60s
  • Q3
    Where are adult stem cells found?
    in sex cells
    bone marrow
    embryos
    in the blood
    30s
  • Q4
    What are embryonic stem cells?
    stem cells from embryos that can differentiate into any specialised cell
    stem cells found in sex cells that from embryos
    stem cells from embryos that can differentiate into only one type of specialised cell
    stem cells from adults that can only differentiate into certain specialised cells
    60s
  • Q5
    Where are embryonic stem cells found?
    the bone marrow
    early human embryos (usually from spare embryos from fertility clinics)
    the blood of newborn babies
    reproductive systems
    60s
  • Q6
    What do you call the type of cloning where a patient’s cells are used to create an early embryo clone of themselves so stem cells can be collected from the embryo to treat the patient’s medical conditions?
    tissue culture cloning
    therapeutic cloning
    adult cell cloning
    embryonic cell cloning
    60s
  • Q7
    Which of these factors is an ADVANTAGE of using therapeutic cloning?
    can take a long time for a suitable donor to be found
    stem cells from the embryo are not rejected when transplanted because they have the same genes as the patient
    can only differentiate into some specialised cell types, so treat fewer diseases
    ethical issues surrounding their use, as every embryo is a potential life
    60s
  • Q8
    Which of these factors is an ADVANTAGE of using adult stem cell treatment?
    stem cells from the embryo are not rejected when transplanted because they have the same genes as the patient
    fewer ethical issues as obtained from adults who can consent to their use
    ethical issues surrounding their use, as every embryo is a potential life
    can only differentiate into some specialised cell types, so treat fewer diseases
    60s
  • Q9
    Which of these factors is NOT a DISADVANTAGE of using adult stem cell treatment?
    uses an embryo therefore can raise ethical issues
    can take a long time for a suitable donor to be found
    donor stem cells may be rejected by the host
    can only differentiate into some specialised cell types, so treat fewer diseases
    60s
  • Q10
    Which of these factors is NOT an ADVANTAGE of using embryonic stem cells?
    have the potential to treat a wide range of medical issues
    can differentiate into any specialised cell, so can be used to treat many diseases
    potential risks involved with treatments, such as transfer of viral infections
    easier to obtain as they are found in spare embryos from fertility clinics
    60s
  • Q11
    Which of these factors is NOT a DISADVANTAGE of using embryonic stem cells?
    Embryos could come to be viewed as a commodity, and not as an embryo that could develop into a person.
    potential risks involved with treatments, such as transfer of viral infections
    can only differentiate into some specialised cell types, so treat fewer diseases
    ethical issues surrounding their use, as every embryo is a potential life
    60s
  • Q12
    What are the cells in an area where rapid cell division occurs in the tips of roots and shoots plants called?
    plant embryonic cells
    meristems
    mericells
    plant stem cells
    60s
  • Q13
    Which of these factors is NOT an ADVANTAGE of using plant meristems to clone plants?
    unknown long term effects of plants if cross pollinate with other plants
    rare species can be cloned to protect them from extinction
    crops can be grown with advantageous features
    plants with special features (e.g., disease resistance) can be cloned to produce many copies
    60s
  • Q14
    Which of these factors is a DISADVANTAGE of using plant meristems to clone plants?
    new plants will grow too quickly
    rare species can be cloned to protect them from extinction
    no genetic variation, so, for example, an entire cloned crop could be destroyed by a disease
    plants with special features (e.g., disease resistance) can be cloned to produce many copies
