Adriana Rempson Mrs. Steeger AP Biology-7 10 October 2012 Transpiration in Plants Abstract: Our group wanted to see how transpiration would happen in plants when they were in different environments. The different environments we used were humidity and room environments. We measured transpiration using the whole plant method. Our results showed that the plants in a humid environment had greater transpiration rates than the plants in the room environment. Introduction: Pants absorb and
