  1. Provide the reason why cells remain small.
    If they are to big they explode
  2. Calculate the surface area to volume ratio for two example cubes.
    3 x 3 x 6 and 3 x 3 x 3 then s/v and reduce always () x () x 6. They want a large S/V ratio
  3. Provide four features that are shared by all cells.
    Cell membrane, cytoplasm, DNA, organelle
  4. Name two broad categories of cells.
    • Procaryotic
    • Eukaryotic
  5. Name four differences between Eukaryotes and Prokaryotes.
    • Procaryotic: DNA in cytoplasm, no nucleus, single cell, not membrane bound
    • Eukaryotic: DNA in nucleus, has nucleus, multi cell, membrane bound
  6. Name the function of the following organelles; Nucleus
    Stores DNA
  7. Name the function of the following organelles; Ribosomes
    Protein maker by using amino acid
  8. Name the function of the following organelles; Endoplasmic Reticulum
    Transports proteins: rough has ribosomes smooth doesn’t
  9. Name the function of the following organelles; Golgi Apparatus (Body)
    Packages and processes proteins launches proteins in vesicles
  10. Name the function of the following organelles; Vacuole
    Vacuole are storage tanks
  11. Name the function of the following organelles; Lysosome
    Lysosomes break down dead cells
  12. Name the function of the following organelles; Mitochondrion
    Power house to cell provides energy for cell
  13. Name the function of the following organelles; Chloroplast
    Takes energy from sun and makes sugar
  14. Name two places within the cell where ribosomes are found.
    Rough ER and Cytoplasm
  15. Describe the difference between rough and smooth ER
    Rough has ribosomes smooth doesn’t
  16. Where are Ribosomes made?
    Nucleolus
  17. Name (at a minimum) two differences between plant and animal cells
    Plants have chloroplasts and have cell walls
  18. Match these key terms to their respective definition: cell, organism, cell membrane, cytoplasm, organelle, chromatin, DNA, nucleolus
    • Chromatin is strand of DNA
    • Organelle little organ
  19. Draw a flow chart that demonstrates your knowledge of cellular metabolism / respiration that includes the: mitochondria, glucose (C6H1206), H20, O2, CO2, H+ions, ADP and ATP.
