Solution
The
absorption of soil nutrients by the roots
of plants occurs in two main phases – apoplast and symplast.
During the
initial phase or apoplast, there is a rapid uptake of nutrients from
the soil into the free spaces of plant cells. This process is passive
and it usually occurs through trans-membrane proteins and
ion-channels.
In the
second phase or symplast, the ions are taken slowly into the inner
spaces of the cells. This pathway generally involves the expenditure
of energy in the form of ATP.
