Why do plant root hair cells use active transport to take in minerals?

  • Minerals are dissolved in water in the soil.

  • Minerals are needed by the plant in very low concentrations.

  • Minerals are present at very high concentrations in the soil.

Scientists want to make human stem cells from body cells rather than getting stem cells from embryos.

Why is this?

  • Human embryos are single-celled.

  • Some people object to destroying human embryos.

  • Stem cells cannot be found in human embryos.

  • The cells in human embryos are all differentiated.

Why are stem cells useful for repairing damaged tissues?

  • They are easily obtained from any organ.

  • They are not attacked by pathogens such as bacteria.

  • They are haploid.

  • They can divide to form different types of cell.

An experiment is carried out to find the concentration of potato tissue.

Four chips are cut from a potato.
q1-paper1h-june2019-ocrgcsebio





At the start, each chip is 50mm long, 10mm wide and 10mm high.

Each chip is put in a different sucrose solution A, B, C and D.

The volumes of the chips are calculated after 1 hour.

Sucrose solution Volume of chip (mm3)
A 50
B 500
C 5000
D 50000


Which sucrose solution has the same concentration as the potato tissue?

In people with multiple sclerosis their immune cells stop working as they should. HSCT is a treatment for multiple sclerosis which destroys all the immune cells.

Once the immune cells are destroyed, cells from a patient’s bone marrow can replace the immune cells.

  • Neurone cell

  • Red blood cell

  • Stem cell

  • White blood cell
