6.Anatomy of Flowering Plants
normal
Trees may be damaged by animals which rub against them, wearing away a strip of bark right around the tree trunk and exposing the xylem. The tree will then
A
Die quickly, because the leaves are deprived of food and water
B
Die quickly, because fungi enter the trunk through the wounds
C
Continue to grow, because bark always regrows to cover a wound
D
Die slowly, because the roots cannot replenish their food reserves
Solution
(a) The tree will then die quickly, because xylem is a conducting tissue which conducts water and mineral nutrients upwards from the roots to the leaves.
When xylem and phloem are exposed it is not able to do work properly hence leaves are deprived of food and water.
