AP Biology Lab #9 - Dublin Unified School District

Each lab group will expose one plant to one treatment. Make sure the tip of a 0.1 ml pipette is inserted into a 16-ince piece of clear plastic tubing. Submerge the tubing and pipette in a shallow tray of water. Draw water through the tubing using a syringe, until all bubbles are eliminated. Carefully cut the plant stem under water. ................
