Lab 9: Transpiration Lab Investigation (4 Lab Stations)


Use a potometer that students assemble to accurately measure water loss in plants.

Your class will apply their knowledge of water potential, learned in AP Lab #1, to the movement of water within a plant. The students will assemble a potometer and use it to measure transpiration under various environmental conditions. They'll also prepare microscope slides of thin sections of a stem to study its organization and identify the structures used by plants to transport water and nutrients throughout the body of the plant. The investigation includes a unique hand microtome that can be used to prepare slides of thin sections of the stem.

Includes comprehensive coverage of transpiration in plants, along with illustrations of root and stem structures such as xylem and phloem. 4 Lab stations.
