Detailed explanation-1: -Answer. Explanation: On a warm dry day, rate of transpiration will increase which will result in faster transport of water and minerals to leaves of trees.
Detailed explanation-2: -We have previously noted Loftfield’s observations that, as water deficiency increases, the stomata close earlier in the day and finally in case of extreme water deficiency reverse their normal behavior and are closed all day and open all night.
Detailed explanation-3: -If plants from a moister region are transferred to a drier region, it is likely that their stomata will remain closed for a longer time, because the time during which stomata are open will be reduced to lower the loss of water via transpiration.
Detailed explanation-4: -Second, stomatal closure reduces evaporative cooling, which can warm the leaf, increasing humidity in the leaf intercellular airspaces and thereby enhancing evaporative demand.
Detailed explanation-5: -Final answer: The cause of guttation is mainly root pressure.
