answer two question about water potential distribution from a prescribed rate of transpiration

Answer two questions about Water Potential Distribution from a Prescribed Rate of Transpiration. More information is in the document.

(1-1) Solve for the water potential of the soil in the hydraulically connected system illustrated below, expressing your answer in megapascals [MPa], and using the flux-gradient equation.

(1-2) List and briefly explain (two to four sentences) 5 different things (environmental conditions or plant attributes) that might act to increase the instantaneous transpiration rate of a whole plant. In all cases explain the physical attributes or mechanisms that would cause an increased rate of transpiration.
