DENDROLOGY

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.

Detailed explanation-3: -Phloem tissue transports organic substances in plants. These organic substances include sugars, such as sucrose, and some mineral ions, which travel as the dissolved form of sap. They go to storage organs and growing areas of the plant. The process is known as translocation.

Detailed explanation-4: -Phloem transports photosynthetically prepared food materials from the leaves to the storage organs and later from storage organs to the growing regions of the plant body. Phloem tissue helps to transport carbohydrates from sources to sinks through the sieve elements.

Detailed explanation-5: -Sugars (usually sucrose), amino acids and other organic molecules enter the sieve elements through plasmodesmata connecting them to adjacent companion cells. Once within the sieve elements, these molecules can be transported either up or down to any region of the plant moving at rates as high as 110 m per second.
