Phloem is a conductive (or vascular) tissue found in plants.

Phloem carries the products of photosynthesis (sucrose and glucose) from the leaves to other parts of the plant. The corresponding system that circulates water and minerals from the roots is called the xylem. But unlike its xylem counterpart, phloem tissue is alive, and is a complex tissue composed mostly of two types of cells:

Sieve tubes - these are cells which have no nucleus, elongated and joined end on end to form long straw-like tubes. These cells are joined to each other by perforated connectors called sieve plates.

Companion cells - are fully functioning cells that assist the sieve tubes by performing cellular functions that the sieve tubes (lacking nuclei, ribosomes, and vacuoles) cannot.

Maple syrup comes from the phloem (sap) of a maple tree.
