Detailed explanation-1: -Organic molecules such as sucrose and amino acids move from a source to a sink via phloem tubes in plants. The phloem is composed of living tissue called sieve tube members (lack a nucleus) that are joined end to end to form a tube that conducts food materials throughout the plant.
Detailed explanation-2: -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-3: -Stem helps in transportation of food and water to different parts of the plant.
Detailed explanation-4: -Sucrose synthesized in green leaves is transported via the phloem, the long distance distribution network for assimilates in order to supply nonphotosynthetic organs with energy and carbon skeletons.
