3.2 Transport in Plants

Osmosis and movement of water through plants

  • Can you write a definition for osmosis?
  • Do you understand that movement of water into and out of cells happens by osmosis?
  • Why is it important in plants to have turgid cells?
  • How would you carry out experiments to demonstrate osmosis using living and non-living systems?
  • Why do multicellular organisms need a transport system?
  • How is water absorbed by root hair cells?
  • What is transpiration?
  • What is the role of xylem?
  • Can you describe the role of phloem?
  • How do changes in humidity, wind speed, temperature and light intensity affect the rate of transpiration?
  • What experiment would you perform to investigate the role of environmental factors in determining the rate of transpiration from a leafy shoot?
