Transpiration in Plants
Objectives
• To state timing and coordination of biological mechanisms involved in growth, reproduction, and homeostasis depend on organisms responding to environmental cues
• To explain that transpiration involves the evaporation of water from the internal surfaces of leaves followed by diffusion of water vapor to the atmosphere
• To explain how the behavioral and/or physiological response of an organism is related to changes in internal or external environment
• To determine the rate of transpiration using potometers
• To test the effect of temperature or humidity on transpiration rates
