Answer 1

Water potential is generally most negative in mesophyll cell walls because water evaporates from the mesophyll cells into the air spaces in the leaf. If the air surrounding the leaf has less water vapor than the air in the intercellular spaces, water vapor will leave the leaf through stomata. Order of water to move through the plant from the soil to the air ( a process called transpiration).

W.P root ---> W.P stem ---> W.P leaf ---> W.P atmosphere.

So, the correct option is 'mesophyll cell walls'.
