Lab 11: Plant transpiration1. In which specific type of tissue in a vascular plant water transported? ______________________ 2. In which specific type of tissue in a vascular plant are products of photosynthesis transported? _________________________ 3. Water exits a plant through the openings in leaves called ___________________________ 4. The ?state? that is kept steady in the Steady State Diffusion Porometer is the _________________ ________________ in the cuvette. 5. Pairs of cells surrounding the stoma are known as ________________ __________________. 6. Abscisic acid sensors are located in the __________________ __________________ of plants. 7. The application of abscisic acid simulates __________________-_________________ in plants. 8. Plants use sunlight and ________________ in the process of photosynthesis to produce ___________________ and _____________________. 9. The _____________-________________ theory of water transport in plants states that water moves through the cells of the xylem under negative pressure. 10. When the concentration of carbon dioxide within a leaf increases, guard cells lose ________________ _______________ and stomata close. 11. Guard cells have ____________________ _________________ sensors. 12. The scientific name of the plant used in this laboratory exercise is _______________________ _____________________. 13. Chlorophyll autofluoresces in the _____________________ range when excited with ____________________-___________________ light. 14. On the other hand, lignin autofluoresces in the _____________________ range when excited with ______________________-_______________________ light. 15. _______________________ is a complex strengthening compound found in the secondary wall of certain plant cells. 16. Most plants have a greater abundance of stomata on the _______________________ leaf surface. 17. The first part of the laboratory activity compares the effect of different __________________ levels on the transpiration rate. 18. The second part of the laboratory activity compare the effect of ____________________ or ________________ on the transpiration rate. 19. __________________ and _____________________ exit leaves through the stomata and __________________________enters the leaves through the stomata 20. _____________________ ___________________ will be used to make epidermal leaf impressions. 21. The lab activities will be done on the ________________________ leaves of the bean plants. 22. The control solution for the second lab activity uses a mixture of 1% __________________ mixed with 99% water. 23. In what units will the transpiration rate be measured by the steady state porometer? __________________________________ 24. What units will the quantum flux density be measured? ___________________________________ 25. Crystal violet stains the middle lamella __________________, stains starch __________________ and stains mucilage __________________.
