Which specialized tissues in vascular plants are responsible for the bidirectional translocation of organic food nutrients synthesized during photosynthesis?

💡 Solution & Explanation

Phloem tissue transports organic nutrients, particularly sucrose and amino acids, from source tissues like mature leaves to sink tissues such as roots, fruits, and growing meristems in both upward and downward directions. Xylem tissue conducts water and dissolved mineral ions unidirectionally from roots to leaves. Sclerenchyma and collenchyma provide structural support and mechanical strength.
