Which plant tissue is responsible for the transport of synthesized food materials from leaves to other parts of the plant?

A. Xylem
B. Phloem✓ Correct Answer
C. Cortex
D. Pith

💡 Solution & Explanation

Phloem tissue is responsible for the translocation of organic nutrients, primarily sucrose and amino acids, synthesized during photosynthesis from source tissues to sink organs across the plant body. In contrast, xylem tissue performs the entirely separate mechanical and physiological function of conducting water and dissolved minerals upwards from the roots. Phloem transport is bidirectional, driven by hydrostatic pressure gradients as explained by the pressure-flow hypothesis.
