SA:V Ratio

  1. 1 cm cube
  2. Smallest one was most effective because it has less volume so has to suck up less. Surface area, temperature, are factor that determine how materials diffuse into cells.
  3. When they grow volume also grows so diffusion is less effective.
  4. 5:2 would have maximum diffusion
  5. Bacteria is just one cell they can divide and have bigger SA
  6. A multicellular organism has a longer lifespan than an unicellular organism and since it has multiple cells, it can perform more functions than a unicellular organism.They can do lots of other things that a unicellular organism can not because it has more cells to complete more jobs
