The sieve tubes of the phloem cells help to transport sugars. The stem of the plant has a layer of cells called phloem. Part of the phloem is made of sieve tubes that permit the flow of sugars solution through the influence of fluid pressure differential. The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.

Both are different structurally and functionally. The xylem cosists of Vessels, trachieds, and parenchyma and is responsible for conduction of water and minerals. the phloem consists of sieve tubes, companion cells and phloem parenchyma and is responsible for conductions of prepared food material in different parts of the plant.
Xylem is different from phloem structurally and functionally.Xylem consists of Tracheids, vessels and xylem parenchyma whereas phloem consists of Sieve tubes, companion cells and phloem parenchyma.Xylem conducts water and minerals to the leaves whereas phloem transports the prepared food from leaves to different parts of plant body.
Phloem (Sieve tubes)
Phloem vessels,the sieve tubes.
Phloem vessels,the sieve tubes.
The cells having sieve like perforations in their cell walls present in phloem are the sieve tubes of the phloem.

Sieve tubes are located in the phloem tissue of vascular plants.
The two main tubes in a plant stem are the xylem and phloem. The xylem transports water and minerals from the roots to the rest of the plant, while the phloem transports sugars produced during photosynthesis to various parts of the plant for energy.

Sieve tubes
The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.
