Which of the following cells primarily transport sugars over long distances?

B) collenchyma cells
C) sclerenchyma cells
D) tracheids and vessel elements
E) sieve-tube elements

Question

Quizplus · Accepted Answer

Sieve-tube elements are specialized cells in phloem tissue that are responsible for transporting sugars and other organic compounds over long distances within a plant. They form long chains called sieve tubes and are connected to each other by sieve plates, which allow for the movement of sugars from one cell to the next. Parenchyma, collenchyma, and sclerenchyma cells are not primarily involved in long-distance sugar transport. Tracheids and vessel elements are involved in water transport in the xylem.
