Answer
Sieve tubes are specialized for transporting nutrients in plants and are alive, while sieve cells are more primitive and lack nuclei at maturity. Both have sieve plates, but sieve tubes are longer and have more specialized pores for efficient transport. Therefore, the correct answer is D. Having sieve pores at end walls.
