Detailed explanation-1: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
Detailed explanation-2: -Phloem. The phloem is responsible for translocation of nutrients and sugar like carbohydrates, produced by the leaves to areas of the plant that are metabolically active. It is made up of living cells.
Detailed explanation-3: -Plant Parts-Stems The cells that do this work are called the xylem cells. They move water. The phloem cells move the food.
Detailed explanation-4: -The stem conducts water and nutrient minerals from their site of absorption in the roots to the leaves by means of certain vascular tissues in the xylem. The movement of synthesized foods from the leaves to other plant organs occurs chiefly through other vascular tissues in the stem called phloem.
