  1. Plant Transport Investigation petehamiltonsandringham college

  2. Transpiration Translocation

  3. Radioactive counts using wood and bark pieces after application of radioactive 42K+to seedling roots 40 40 40 35 55 45 Disrupts Phloem 60 70 75 100 100 source source

  4. The Effect of Blocking Stomata Radioactive phosphate + water in veins Photosynthesis resulting in radioactive carbohydratesb No radioactive phosphate under the BS as water vapour cannot escape thro the stomata Blocked stomata prevent intake of radioaactive CO2 No radioactive CO2 in veins or under BS Transpiration

  5. Stomata – pores in the epidermis allow movement of gases into and out of the leaf tissue. Guard cells open and close these pores to aloow gaseous exchange without excessive water loss.

  6. Open when Turgid Ie. water available Closed when flaccid Ie.less water available
