would sweet potatos have a high water potential than russet potatos?

Expert Solution

Sweet potato and russet potato water potential

Water potential is the tendency of water to move from one area to another due to osmosis. In osmosis water moves from low solute concentration to high solute concentration through semipermeable membrane. Sweet potato contain high sugar content as compare to russet potato. To check the hypothesis of water potential the both potato kept high sugar concentration solution and in distilled water separately. Sweet potato gain the weight in distilled water while they lose their weight in the highly concentrated sugar solutions. But when we follow the same process for russet potato the change in the weight is very less as compare to the sweet potato. This is happen because high concentration of solute (sugar) in sweet potato. So it would clearly suggest sweet potato have high water potential then russet potato. The water potential is influenced by solute concentration, pressure, gravity, and factors called matrix effects. Water potential denoted by the equation.

Ψ (water potential) = Ψs + Ψp + Ψg + Ψm

Where

Ψs = solute potential

Ψp, = pressure potential

Ψg, = gravity potential

Ψm = matric potential
