Question

Removal of ring bark would finally lead to the death of plant due to
A. Absence of transport of minerals
B. Absence of transport of organic solutes to roots
C. Death of stem
D. Absence of water translocation

Answer 1

Hint: Bark is the part of the woody plants. It is the outermost layer of the stem and roots of woody plants. We will first explain the whole process of removal or ring bark and then we will conclude our answer.

Complete Answer:
- Removal of ring bark is called ring barking or girdling.
- It is the complete removal of the strip of bark from around the entire circumference of a stem of a woody plant.
- The Strips of bark consist of cork, cambium, phloem, cambium and sometimes a part of xylem.
- So, due to the removal of these tissues from the plant transport of organic solutes to root stops.
- So, the roots are starved and the entire plant leads to death.

Factors responsible for girdling:
(I) Human practices – horticulture, forestry
(II) Animals – such as rodents. They girdle trees by feeding on outer bark.
Herbivorous animals, Birds, Insect
Therefore, it is clear from the above discussion that the removal of ring bark would finally lead to the death of plants due to absence of transport of organic solutes to roots.

Hence, option B will be the right option.

Note: Remember to keep in mind that ring barking can be useful. Orchardists use ring barking as a cultural technique to yield larger fruit.
