Asexual reproduction…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.
