phloem tubes transport dissolved sugars from the leaves to the rest of the plant (food)
phloem is made of columns of living cells with small pores that allow cell sap to flow through
phloem transports dissolved sugars from the leaves to the rest of the plant for immediate use or storage . the transport goes both directions, this process is called translocation
xylem tubes take water up from the roots to the leaves and transport it to the stomata
xylem is made from dead cells strenghtened by lignin
xylem carries water and mineral ions from roots to stem and leaves
the movement of water from roots, through the xylem and out the leaves is called the transpiration stream
