The concept that xylem only transports water/minerals and phloem only transports organics is no longer strictly accurate because:
Show answer and explanation
Correct answer: Small amounts of material are exchanged between xylem and phloem.
Chemical analysis reveals that there is an exchange of materials between xylem and phloem. Both organic and inorganic solutes can be found in both tissues, though they have primary roles.
