The translocation of minerals from roots to leaves occurs through:

Unlike water,all minerals cannot be passively absorbed by the root because the concentration of minerals in the soil is usually ....... than the concentration of minerals in the root.

Write a short note on the uptake of mineral ions.

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?

If the amount of an ion absorbed by a root hair cell at $0^o C$ is $5 \ gm$ and at $20^o C$ is $20 \ gm$,then the amount of this ion absorbed actively should be (in $gm$)

Into what do mineral ions enter from the cell walls of the root?
