Question

In a ring girdled plant:

• A. Neither root nor shoot will die
• B. The shoot dies first
• C. The root dies first
• D. The shoot and root die together

Answer 1

The correct option is C The root dies first

Girdling is the removal of a ring of outer tissue up to the depth of the phloem layer in a woody trunk.
Phloem is responsible for downward movement of food, which is stopped by girdling.
Therefore, the roots will not be able to get food and die first.
