Question
Chapter 29.6, Problem 3CC
Summary Introduction
To explain:
The lowering of temperature of the leaves by the evaporation.
Introduction:
The process of loss of water through the stomata pores present on aerial parts of shoots is called transpiration. A large volume of water is absorbed by the roots of the plant, but a portion of it is used for plant growth and its

- 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.arrow_forwardSCIENTIFIC INQUIRY • INTERPRET THE DATA A Minnesotagardener notes that the plants immediately bordering a walkwayare stunted compared with those farther away. Suspectingthat the soil near the walkway may be contaminated from saltadded to the walkway in winter, the gardener tests the soil. Thecomposition of the soil near the walkway is identical to thatfarther away except that it contains an additional 50 mM NaCl.Assuming that the NaCl is completely ionized, calculate howmuch it will lower the solute potential of the soil at 20°C usingthe solute potential equation:ΨS = -iCRTwhere i is the ionization constant (2 for NaCl), C is themolar concentration (in mol/L), R is the pressure constant[R = 0.00831 (L · MPa)/(mol · K)], and T is the temperature inKelvin (273 + °C).How would this change in the solute potential of the soilaffect the water potential of the soil?
