Question
Chapter 36.4, Problem 4CC
Summary Introduction
To explain: The cooling effect of evaporation on leaves.
Concept introduction: Transpiration is the process of evaporation of water from the leaves of the plant. Water is absorbed by the roots and transported to the leaves. While stomata are open during the exchange of gases, transpiration occurs during photosynthesis.

QUESTION 1
Water potential is the pressure exerted by freely moving water molecules in a
system. Describe the relationship between water potential with solute potential
and
pressure potential in plants.
Plant cell P has a solute potential of-350 kPa and a pressure potential of 200 kPa.
Besides, is plant cell Q which has a solute potential of -500 kPa and a pressure
potential of 200 kPa. Determine the direction of net movement of water between
the two cells by using the water potential equation.
Explain the characteristics of water that make it such an important medium for
life. If an athlete was heavily perspiring after an intense match game, suggest one
type of replacement drink (with explanation) that he should take between
hypertonic, isotonic and hypotonic drink to recover himself.

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_forwardA team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species.
