Which plant tissue is primarily responsible for the upward transport of water and dissolved mineral ions from roots to leaves?

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

💡 Solution & Explanation

Xylem is a specialized complex permanent tissue in vascular plants that facilitates the unidirectional transport of water and dissolved mineral ions from the roots to the stem and leaves. Tissues like phloem are instead responsible for transporting organic nutrients produced during photosynthesis. Transpiration pull and root pressure act as the primary driving forces for this upward movement through xylem vessels and tracheids. Plant anatomy and transport mechanisms are frequently tested in preliminary biology questions.
