Detailed explanation-1: -Phloem is the vascular tissue which transports food from leaves to the other parts of the plant. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibers and phloem parenchyma cells. Whereas xylem transport water and minerals from roots to different parts of the plant.

Detailed explanation-2: -Plant Physiology and Development Phloem is one of the two tissues that make up the plant’s long-distance transport system, the other being xylem. Phloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored.

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: -Final Answer: the movement of food in phloem is called translocation.

Detailed explanation-5: -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.
