The phloem is responsible for transporting sugars produced in the leaves to other parts of the plant, including the roots. If the phloem were to become blocked, sugars would be unable to reach the roots and the plant would be unable to obtain the nutrients it needs. This could ultimately lead to reduced growth or even death of the plant. The blockage of phloem would not necessarily dry out the leaves or prevent water from reaching the roots, as these functions are performed by other tissues in the plant.
