Questions to Answer: 1. Why should the shoot be cut under water? The leafy shoot for a plant should be cut and plunge its base on water. By this, the xylem allows the xylem from taking up any water. Wetting the leaves themselves will alter the rate of transpiration. This requires a large sink. If air gets into the xylem vessels of the plant, it can form air locks which will prevent the plant taking up water and so prevent steady transpiration. Also, the shoot must be cut underwater to ensure that no air or air bubbles enter the stem. Conclusion The difference in the surface area of the two set-ups indicates that there should be difference in the transpiration rates of the plants on different environmental conditions. Light and temperature were the primary factors that affect the transpiration rate of the leaves. Also, transpiration rate could also be affected by the area of the transpiring leaf itself thus, the larger the surface area, the greater the transpiration rate.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
