Quizplus · Accepted Answer

Sieve pores are specialized structures found in phloem cells of vascular plants that facilitate the movement of sugar and other organic compounds throughout the plant. These pores are formed by sieve elements, which are cells that lack a nucleus and other organelles to form long tubes for transporting nutrients. Through these pores, sugars are actively transported from source cells to sink cells, which require energy for growth and metabolism.
