Water Moves Stomata Transpiration Diffusion Open Explain Loss

Front Explain why water loss is inevitable for plants.
Back Why transpiration is inevitable:
  • CO2 moves in and O2 moves out of leaf by diffusion thru stomata
  • When stomata are open to allow gas exhange, water vapour also moves out by diffusion and is lost - transpiration
  • Stomata open/close to control amount of water lost, during the day must be open for photosynthesis but during night closed
