Minerals absorbed by the roots travel up the xylem. How do they reach the parts where they are needed most? Do all the parts of the plant get the same amount of the minerals?

Unloading of the mineral ions occurs via fine vein endings through diffusion and active uptake by the cells. In plants, xylem are involved in transport of inorganic nutrients where phloem transport only organic materials.
Mineral ions are frequently remobilised from older parts of plant like leaves to the younger regions. Elements most readily mobilisal are phosphorus, sulphur, nitrogen, potassium, and some elements that forms the structural component are not remobilised e.g., calcium.
