If the xylem in a young tree is damaged, which process is first affected? a) performing photosynthesis

b) absorbing water from the soil

c) transporting sugar to the roots

d) transporting water to the leaves

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.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
