Answer 2

Answer:

Correct answer : (d) A and B are true

Explanation:

• Xylem parenchyma and xylem fibers are part of xylem elements including tracheids and vessels.
• Xylem parenchyma is the only living component of all the xylem elements.
• They have thin cell walls and a distinct nucleus with a huge vacuole. It helps in the storage of fats, starch, oil, tannins, and other plant metabolites.
• On the other hand, xylem fibers are long elongated, narrow tapering non-living cells. Their cell walls are heavily lignified, which provides great tensile strength and elasticity.
• The main function of xylem fiber is to provide mechanical support and structural integrity.
