SCIENTIFIC 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? In what way would thechange in the water potential of the soil affect the movementof water in or out of the roots?

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.

Most photosynthesis occurs in the cells of the palisade mesophyll and the spongy mesophyll. For photosynthesis to occur, these cells must receive the reactants needed for photosynthesis and be able to allow the products to exit.

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. Water Level in Millititers 20 minutes 69.1 72.0 72.2 71.9 Condition 0minutes 69.1 73.6 73.0 725 10 minutes 69.1 72.8 72.5 72.3 30 minutes 69.1 72.0 71.8 71.9 Total Change Room Fan Light Mist 1.6 1.2 0.6 Part A: Identify the condition that creates the fastest rate of transpiration.
