BOTANY

Detailed explanation-1: -Phloem (/ˈfloʊ. əm/, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation.

Detailed explanation-2: -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-3: -Phloem is composed of living cells that transport a water solution of sugars that we commonly call sap. This movement is modeled by the pressure-flow theory, a part of which is that the sugar-containing fluid is moved through sieve tubes by fluid pressure.

Detailed explanation-4: -Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.

Detailed explanation-5: -There has been a consensus in the phloem transport field for over 50 years that sucrose is the predominant sugar carried in the sieve tubes of most species.
