6. What is resolution?

  • This is the ability to see two objects that are close together as separate objects.
  • This is the ability to see two objects as one
  • clarity of the object

7. What is the function of the chloroplast?

  • This is the site of photosynthesis
  • to build cytoplasm
  • the heart of the cell

8. What is the role of the Golgi apparatus?

  • to process and package proteins (add carbohydrate chains) ready for use outside the cell
  • To control what substances leave or enter the nucleus/ cell
  • To move cytoplasm over the surface of the cell

9. What is the function of the SER? (Smooth endoplasmic reticulum)

  • To help by producing chloroplasts for photosynthesis
  • To manufacture lipids (fats and oils) and transport them
  • To build ribosomes

10. What is the function of the Flagella?

  • It is responsible for cell movement
  • It is responsible for cell reproduction
  • It is responsible for cell growth

11. What do Golgi vesicles do?

  • enter the nucleus if it needsrepairing
  • Transport proteins to the plasma membrane for use outside the cell
  • Build the golgi appartus

12. SEM: What is their maximum resolution

  • SAME AS TEM = 0.1 - 0.2 nm
  • DIFFERENT TO TEM - 1 - 2 nm
  • 0.01 - 0.02 nm

13. SEM: What is their maximum effective magnification?

  • x 50,000
  • x100,000
  • x 400

14. What is the maximum resolution power of a light microscope?

  • 20 nm
  • 200 nm
  • 400 nm

15. TEM: What is their maximum effective magnification?

  • x50,000
  • x500,000
  • x100,000

16. What is the role of the Cilia?

  • To be smaller than the flagella yet fatter to keep the cell anchored well
  • It is responsible for the movement of liquids over the surface of the cell and contain microtubules
  • To be bigger than the flagella

17. What is the function of the ribosomes?

  • Site of protein synthesis
  • The site of photosynthesis
  • To fix damaged tissue

18. What is the function of the nucleolus?

  • The brain of the cell - controls the cell
  • produce ribosomes
  • structure the nucleus

19. What are the roles of the centriole?

  • These produce spindle fibres which move chromosomes in nuclear division
  • to produce spindle which fix damaged cell organelles
  • to produce fibres that harness liquids moving over the cell for use inside the cell

20. TEM: What is their maximum resolution?

  • 0.1 - 0.2 nm
  • 1 nm
  • 2 - 4 nm
