What is the primary function of xylem tissue in vascular plants?
Answer and explanation
Correct answer: B. Transporting water and dissolved mineral salts unidirectionally from roots to aerial parts
- Step 1: Xylem consists of tracheids, vessels, xylem parenchyma, and xylem fibers.
- Step 2: Driven by transpiration pull and root pressure, xylem conducts water and dissolved mineral ions upward from roots to stems and leaves.

Transporting water and dissolved mineral salts unidirectionally from roots to aerial parts.
Why not the others: Phloem translocates soluble organic nutrients bidirectionally; storage parenchyma stores starch; and mesophyll cells synthesize chlorophyll.
