In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, sucrose, a sugar, to all parts of the plant where needed.In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word ÏÎ»Î¿Î¹ÏÏ (phloios) meaning bark.n vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, sucrose, a sugar, to all parts of the plant where needed.
The two types of vascular tissue are xylem (dead cells) and phloem (living cells). The xylem carries water and dissolved minerals upward from the roots through the stem and leaves of the plant. Phloem is responsible for distributing the products of photosynthesis, such as amino acids and carbohydrates, from the leaves to the rest of the plant.
