6. What is needed if a protein is produced?

  • The DNA needs to make proteins
  • The protein needs to be correct
  • The gene needs to be switched on
  • The gene needs to be switched off

7. What does glandular tissue do?

  • Contracts to release digestive juices
  • Churns food and and digestive juices
  • Releases digestive juices e.g. enzymes
  • The inner/outer layer of cells

8. What's the fancy word for when the water outside and inside a plant cell is equal

  • Turgid
  • Cell membrane
  • Flaccid
  • Vacuole

9. What does muscle tissue do?

  • Separates food and digestive juices
  • Contracts to churn food and and digestive juices
  • Contracts to release digestive juices
  • The inner/outer layer of cells

10. Name when osmosis will occur into the cell

  • Turgid - Hypotonic
  • Flaccid
  • Plasmolysed - Hypertonic

11. What's the correct statement about a SEM?

  • Samples can be live or dead
  • It has a higher resolution that TEM
  • It has a lower magnification that TEM
  • It's 2D

12. What's the carbon dioxide conc. like inside a leaf compared to the air outside

  • It's lower because it's being used up in cells
  • It's higher because it's being produced in the cells

13. What's the oxygen conc. like inside a leaf compared to the air outside

  • It's higher because it's being produced in the cells
  • It's lower because it's being used up in cells

14. What happens if specialised cells work together?

  • They make organs
  • They make tissues
  • They make cells
  • They make specialised tissue

15. Pick the equation relating image size, magnification and specimen size

  • image size = magnification/specimen size
  • specimen size = image size x magnification
  • magnification = image size/ specimen size
  • magnification = image size x specimen size

16. What is different about active transport and why?

  • It goes against the concentration gradient because it needs energy from mitochondria
  • It goes against the concentration gradientso therefore doesn't need to go against the concentration gradient
  • It doesn't go across a partially permeable membrane so it needs lot of energy
  • It doesn't go across a partially permeable membrane so it doesn't need energy

17. What does DNA do?

  • Makes nucleotides
  • Makes different proteins
  • Codes for different proteins
  • Makes sure the cell is working

18. What is a plant stem cell?

  • A cell that will differentiate into an unspecialised cell
  • A specialised cell that can differentiate into any type of plant
  • An unspecialised cell that can differentiate into any type of plant
  • A cell that can become specialised

19. Name when there is no net movement in osmosis

  • Turgid - Hypotonic
  • Flaccid
  • Plasmolysed - Hypertonic

20. What is differentiation?

  • When an undifferentiated cell turns into a differentiated cell
  • When a differentiated cell turns into an undifferentiated cell
  • When an unspecialised cell turns into a specialised cell
  • When a specialised cell turns into an unspecialised cell
