Sucrose Concentration and Water Potential by Kevin Gayle https://padlet.com/kevin_gayle/1urvz5lchpdu If you have argument that works, put it here please! en-us 2018-11-06 00:30:55 UTC 2019-10-09 14:46:47 UTC hello@padlet.com Questions kevin_gayle https://padlet.com/kevin_gayle/1urvz5lchpdu/wish/301333730
  • Co-transport: Where is the highest sucrose concentration, inside or outside the cell?
  • Water potential: What causes the water potential outside the leaf to be lower than inside the leaf?

    R2: More water molecules move out of the leaves through stomata than the water goes in. Thus the overall movement of water is down the concentration gradient.
    R3: There is no partially permeable membrane in stomata.
    R4: Any gas other than water vapour, CO2 for example, can go out of the leaf, as long as its concentration inside the leaf is greater than outside.
    C: This movement of water molecule should be regarded as diffusion instead of osmosis. Therefore we don't need to compare the water potential inside and outside of the cell.]]>     2018-11-07 12:00:36 UTC https://padlet.com/kevin_gayle/1urvz5lchpdu/wish/301431486     Question 1 https://padlet.com/kevin_gayle/1urvz5lchpdu/wish/301461036 i think this is depends on the water concentration of the solution inside the cell compared to water concentration of the solution outside the cell.

    Ψs =  solute potential
    Ψp, = pressure potential 
    outside the leaf the  solute potential and pressure potential always larger than the leaf inside, also the leaf lose the water by transpiration so inside the cell the water potential always smaller than outside.
