Which statement is correct? None of the statements are correct. On a very still (little wind) day, the microclimate at the leaf surface has a low water potential, thus there is little transpiration loss. On a very windy day, the microclimate at the leaf surface has a high water potential, thus there is a lot of water lost via transpiration. On a very still (little wind) day, the microclimate at the leaf surface has a high water potential, thus there is little transpiration loss.

Considering the concepts of hydraulic lifting and water potential, which of the following statements is like not true about the figure/illustration below? * DRY DRY WET The water generally moves from wet soil patches to dry soil patches because the latter have lower water potential. A deep-rooted plant can send water to dry soil patches with lower water potential O while simultaneously absorbing water from deep soil layers with higher water potential. The plant has higher water potential than the wet soil patches, but lower water potential than the dry soil patches. The plant has lower water potential than the wet soil patches, but relatively higher water potential than the dry soil patches.
Two plants are in a set-up wherein they are exposed to wind (fan). Plant 1 had a transpiration rate of 1.15 while Plant 2 had a transpiration rate of 1.86. Your primary goal is to conserve water. Based on the given, which plant is not suited to be planted in windy slopes of the watershed?
It is June in Fresno and the officials at the water district have just reduced your irrigation ration by 26%. In the field, you determine that the water potential in your soil is -1.68 MPa while the water potential of your crop is -1.62 MPa. Question A. Is your crop able to take up water from the soil? Explain. Question B. It is now late August and your soil water potential is -2.10 MPa, fortunately, you have been granted one magic wish in altering the physiology of your crop to increase its ability to take up water, however, you must choose from one of the options below. Fill in the values denoted by the ? as needed, and select the option that will cause the greatest water uptake by your crop. Option Vs (MPa) Vp (MPa) Vw (MPa) -1.90 0.00 -2.59 +0.13 -2.4 -2.09 -2.05 -2.28 +0.17 4.
Transpiration harnesses the force of gravity to accelerate water transportation from the soil to the leaves. True O False
Two plants are in a set-up wherein they are covered by plastic. Plant 1 had a transpiration rate of 1.15 while Plant 2 had a transpiration rate of 1.86. Your primary goal is to conserve water. Based on the given, which plant is adapted more naturally in forests wherein there is a high humidity?
What does hydraulic conductance mean in the following? The hydraulic limitation hypothesis proposes that reduced growth in taller trees is caused by decreased photosynthesis resulting from a decrease in hydraulic conductance promoted by a longer root-to-leaf flow path.
Scientists studied what caused leaf shedding in a drought deciduous (=shedding leaves during the dry season) subtropical species. They quantified the quantum yield (=efficiency) of the PSII complex and the leaf hydraulic conductance (=efficiency of leaf water movement) in leaves of that species during the wet to dry transition Explain the results in the context of what could drive leaf shedding in this species? Figure 1. Changes in leaf hydraulic conductance during the wet and dry season transition of a subtropical species
Turgor pressure in a plant is directly related to the amount of water within the chloroplasts of the plant cell. how quickly nutrients can be absorbed from the soil. the amount of water within the central vacuole of the plant cell. the number of vacuoles within a plant cell. how quickly water can be absorbed through the roots.

Describe how the water potential of a leaf changes throughout the course of a 24-hour period. What is driving this change? How does the water potential of this leaf compare to the water potential of a root in the same plant during the same period? How does it compare to the soil underneath the plant?
