Question

In which direction does water always move, regardless of differences in potentials, through a low hydraulic conductivity soil?

a) From a high potential to a low potential
b) Not affected by differences in potentials
c) From a low potential to a high potential
d) Faster through a low hydraulic conductivity soil

Answer 1

Water moves from high to low potential in soil, even if the hydraulic conductivity is low. This is due to differences in water potential influenced by the concentration of water versus solutes.

Step-by-step explanation:

In the context of soil and water movement, water always moves from a high potential to a low potential, which is described in terms water potential and hydraulic conductivity. For soil with low hydraulic conductivity, water will still move from areas of high water potential to areas of low water potential. This typically means that water moves from regions where the water concentration is higher (or solute concentration is lower) to regions where the water concentration is lower (or solute concentration is higher). Moreover, during drought conditions, plants adjust their physiological mechanisms, such as closing stomata and shedding leaves, to conserve water.
