Movement into and out of cells — practice question

During an investigation, a leafy shoot was connected to a potometer and placed under several different conditions. For each condition, the length of time for the meniscus to travel $50\,\text{mm}$ through the capillary tubing was measured and noted. Which row represents the slowest and fastest rates of water uptake in this investigation?

  • Aslowest rate $0.3\,\text{mm s}^{-1}$; fastest rate $1.3\,\text{mm s}^{-1}$
  • Bslowest rate $0.3\,\text{mm s}^{-1}$; fastest rate $3.3\,\text{mm s}^{-1}$
  • Cslowest rate $3.3\,\text{mm s}^{-1}$; fastest rate $0.3\,\text{mm s}^{-1}$
  • Dslowest rate $1.3\,\text{mm s}^{-1}$; fastest rate $0.8\,\text{mm s}^{-1}$
