Transport Systems in Plants
Flowering plants have separate transport systems:
Xylem tissue transports: water and mineral ions from: the roots to: the stem/leaves
Phloem tissue transports: dissolved sugars from: the leaves to: the rest of the plant (e.g. growing regions and storage organs)
The transpiration stream is the movement of water from the roots and out of the leaves, via the xylem.
