Which plant tissue consists of dead, hollow, thick-walled lignified cells that provide structural strength and conduct water?

A. Phloem
B. Xylem vessels✓ Correct Answer
C. Collenchyma
D. Parenchyma

💡 Solution & Explanation

Xylem vessels consist of dead, hollow, thick-walled lignified cells that jointly facilitate the upward transport of water and dissolved minerals while providing mechanical support to the plant body. Other tissues such as phloem specialize in the translocation of organic nutrients, whereas parenchyma cells remain living and perform storage functions. This specialized vascular tissue is a hallmark of tracheophytes or vascular plants.
