HORTICULTURE

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: -Reason (R): Xylem transports only inorganic nutrients and phloem transports only organic nutrients. No worries!

Detailed explanation-3: -Inorganic substances (which form the majority of the soil substance) are commonly called minerals: those required by plants include nitrogen (N) and potassium (K), for structure and regulation.
