Part F - How to determine transpiration rates by the whole plant method Which of the following best explains why the plant in front of the fan lost more mass than the control plant in normal room conditions?   The leaves of the plant in front of the fan had the highest initial water potential and therefore lost the most water. The control plant had lower initial water potential in the root area and therefore lost less water. The control plant had a lower initial mass and so lost water at a decreased rate. The fan rapidly moves water molecules away from the leaf surface, lowering the water potential.

Briefly describe the pigments used in photosynthesis, where these pigments are located in the plant, and what these pigments do. Define both absorption spectrum and action spectrum, and describe the purpose of using a spectrophotometer to determine the absorption spectrum and how that correlates to the action spectrum. Be sure to discuss how the spectrophotometer allows the identification of the pigment solutions.

21 RP2_MSY1_SCIENCE of 12 5. A scientist wanted to know how different conditions affect the rate of transpiration in plants. To conduct her investigation, the scientist poured 70 mL of water into four cups. In each cup she placed a plant. Then she placed each cup in a different condition: next to a fan, under a light, next to a misting fan, and one just in the middle of the room. Her data is in the table below.
