Question

In a ring girdled plant

• A. A) root dies first
• B. B) shoot and root die together
• C. C) neither root nor shoot will die
• D. D) shoot dies first

Answer 1

The correct option is A A) root dies first

Ring girdling is also called as ring-barking, it is the complete removal of strip of bark from the tree covering the circumference. This bark consists of phloem, cambium and some times even xylem tissue. Due to this, the connection between phloem tissue breaks and hence food from leaves will not be supplied to the lower part from where the bark is removed. Eventually, thelower part, that is, the root dies.

Girdling is done for human practices like forestry, horticulture, or vandalism. Some times herbivorous animals which feed on tree barks are also responsible for ring girdling.

So, the correct option is 'root dies first'.
