By graphing relative volume and mannitol concentrations, I determined that my ψ for potato tissue and mannitol at equilibrium was -.4. How would I determine the initial ψ for the tissue from this value?
Homework Answers
intial concentration = - i * R * C * T
R is the pressure constant , i is the ionization constant , c is the molar concentration , T is the temperature ,
ψs = [-4]* [ o.831}* [ 273]* {1} = - 90.854

If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase
If a potato core is allowed to dehydrate by sitting in open air, would the water potential of the potato cells decrease or increase? i think it decreases but i'm not sure. and if a plant cell has a lower water potential than its surroundings and if pressure=0, is the cell hypertonic(in terms of solute concentration) or hypotonic to its environment? will the cell gain or lose water? any ideas...?http://en.wikipedia.org/wiki/Water_potentialanalysis queswhat is water potential?Osmosis Lab /27819 Name: ________________________________ Date: ___________...
