Detailed explanation-1: -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. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.
Detailed explanation-2: -Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients.
Detailed explanation-3: -The phloem tissue transports sugars made from the leaves to the rest of the plant. Food is also transported to storage organs. Phloem is a living tissue, phloem cells are alive. The movement of dissolved sugars from the leaves to the rest of the plant is called translocation.
Detailed explanation-4: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
Detailed explanation-5: -In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), particularly sucrose; a sugar, to all parts of the plant.
