Detailed explanation-1: -Xylem sap carries soil nutrients (e.g., dissolved minerals) from the root system to the leaves; the water is then lost through transpiration. Maple sap is xylem sap, containing some sugar in late winter. Phloem, or sieve-tube, sap is the fluid carrying sugar from leaves to other parts of the plant in the summer.
Detailed explanation-2: -The chemical components of xylem and phloem sap are as follows: Xylem sap: In xylem sap the major constituents are water and diluted concentrations of different minerals. It is slightly acidic. Phloem juice: Phloem sap consists of trace elements, water, sucrose and amino acids.
Detailed explanation-3: -Xylem transports only inorganic nutrients while phloem transports only organic materials.
