Which elements of xylem are made up of dead cells and yet are responsible for transporting water and minerals in plants?

Correct option is D

The correct answer is (D)   ​Tracheids and Vessels

• Tracheids and vessels are the two types of dead cells responsible for transporting water and minerals in plants.
• Tracheids are long, thin cells with pointed ends and small openings (pits) in their walls that allow water to pass through. They are found in most vascular plants.
• Vessels are shorter and wider than tracheids, consisting of multiple cells joined end to end. Together, they form continuous tubes that enable faster water flow. Vessels are commonly found in angiosperms and some gymnosperms

Information booster:

• Xylem parenchyma cells are living cells within the xylem tissue. They help store and transport nutrients, as well as water. Their primary functions include storing water, fats, and glycogen.
• Xylem fibers are composed of dead sclerenchyma cells. These fibers provide mechanical support to the plant due to their flexibility and strength but do not directly transport water or minerals.
