The right answer is B) Absorbing water from the soil.
The xylem allows the circulation of the raw sap (water and mineral salts) drawn from the soil by the roots. The circulation is vertical and in the tracheids the presence of a transverse wall causes circulation in a chicane. The xylem also has a supporting role.
The differentiation of procambium is centrifuged in the roots and centripetal in the stems. This difference makes it possible to distinguish a root from a stem.
The secondary xylem, or wood, is characterized by a radial alignment of its cells due to the operation of liberalis cambium (secondary meristem): it is formed in the internal position with respect to cambium and leads to the formation of vessels, fibers, parenchyma vertical and horizontal.
