DENDROLOGY

Detailed explanation-1: -The one word to denote transportation of food via Phloem is “Translocation”. Sucrose and amino acids are transported by Phloem up and down through the plant. The process of translocation involves transportation of food into sieve tubes from where food can travel upward or downward to all the parts of the plant.

Detailed explanation-2: -Food and other organic substances (e.g., some plant hormones and even messenger RNAs) manufactured in the cells of the plant are transported in the phloem. Sugars (usually sucrose), amino acids and other organic molecules enter the sieve elements through plasmodesmata connecting them to adjacent companion cells.

Detailed explanation-3: -Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar.
