Question

One way to kill a tree is to girdle it by cutting a groove a centimeter into the bark all around the trunk of the tree. The tree will typically survive that growing season, but will die over the winter. What is the best explanation for this observation?

Answer 1

Answer:

The correct answer will be - the sugar is not transported to roots

Explanation:

The girdling is performed on tress by making a groove of 1 cm in the bark of a tree.

The girdling activity removes the phloem tissue of the trees which help in the conduction of the sugar and other useful nutrients in the trees.

Since the phloem is present on the outside portion of the vascular cambium due to the secondary growth, therefore, removing the bark and making a groove in the tree removes the portion of the phloem. The removal of the phloem stops the blockage of the sugar to the roots as a result of which the root dies and water is not absorbed. This leads to the death of the tree after some time.

Thus, the sugar is not transported to roots is the correct answer.
