Detailed explanation-1: -Phloem benefits the plant by transporting sugar, amino acids, and other nutrients from the roots to the leaves, stem, and other plant parts. If the phloem is eliminated, there will be no transfer of chemicals and plants will not receive the necessary nutrients to carry out their processes.
Detailed explanation-2: -Injured xylem will carry less water to the branches and leaves. Both of these problems limit the supply of vitally needed water and salts to the leaves. Plants that had little time to prepare for cold temperatures will be more severely injured than those that cooled more slowly.
Detailed explanation-3: -Sucrose transport is favorable for the following reasons: (i) 1 mol sucrose contains more energy than 1 mol of a monosaccharide such as glucose or fructose, thus using the disaccharide is more energy efficient for transport and storage.
