Detailed explanation-1: -The vascular tissue, phloem helps in the transportation of the synthesized food from the leaves to various storage organs. Phloem is a complex permanent tissue that is present in all vascular plants. Phloem consists of various elements-phloem parenchyma, phloem fibers, companion cells, and sieve tubes.

Detailed explanation-2: -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-3: -Phloem transports carbohydrates, produced by photosynthesis and hydrolysis of reserve compounds, to sink tissues for growth, respiration and storage. At photosynthetic tissues, carbohydrates are loaded into phloem (Rennie and Turgeon 2009), a process that raises the solute concentration.

Detailed explanation-4: -Phloem is the plant tissue that conduct food made in the leaves to all other parts of the plant.

Detailed explanation-5: -Phloem parenchyma cells, called transfer cells and border parenchyma cells, are located near the finest branches and terminations of sieve tubes in leaf veinlets, where they also function in the transport of foods.
