In this laboratory exercise, you will investigate different structural and functional aspects of transpiration. You will observe different components of the plant vascular system and conduct an experimental manipulation of corn (Zea mays), a C4 plant, and sunflower (Helianthus annuus), a C3 plant. The results of this exploration will demonstrate the fundamental principles of transpiration and the function of plant structures in this important physiological process.
