1) Tracheids are elongated cells in the xylem of vascular plants that serve in the transport of water and mineral salts. ... Tracheids, unlike vessel elements, do not have perforation plates. All tracheary elements develop a thick lignified cell wall, and at maturity the protoplast has broken down and disappeared.
2) In plant anatomy, sieve tube elements, also called sieve tube members, are highly specialised type of elongated cell in the phloem tissue of flowering plants. The ends of these cells are connected with other sieve tube members, and together they constitute the sieve tube. The main function of the sieve tube is transport of carbohydrates, primarily sucrose, in the plant (e.g., from the leaves to the fruits and roots). Unlike the water-conducting xylem vessel elements that are dead when mature, sieve elements are living cells. They are unique in lacking a nucleus at maturity.
At the interface between two sieve tube members in angiosperms are sieve plates, pores in the plant cell walls that facilitate transport of materials between them.
