A student is performing a chemical analysis of xylem sap. This student should not expect to find much what?

Xylem consists of vessel elements. When a student performs chemical analysis of xylem sap, he should not expect much of sugars (carbohydrates). This is because phloem transports sugar.

Xylem sap however, is fluidic which consists of hormones, minerals and many other nutrients. It transports from roots towards leaves.
