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 ?

Explanation

Absorbed salts reach to various parts of the plant by transpiration through stem. Their main storage place is developing parts of the plant like apical and lateral meristematic tissue, mature leaves developing flowers, fruits, seeds and storage organs.
Xylem tissue moves upward in transport of ions by diffusion and active transport. While organic food is transported by phloem tissue.
Translocation of ions is done from old parts of the plant to matured parts. Some elements like phosphorus, sulphur, nitrogen, potassium and other elements which are present in constituent elements they do not translocate. e.g. calcium.
