Question

When a plant is girdled

• A. The root dies first
• B. The shoot dies first
• C. The root and shoot die at the same time
• D. Neither the root nor the shoot will die

Answer 1

Answer: (A)

The root dies first

In girdling experiments phloem is removed so food cannot be transported to locations beyond the point of girdling. Hence root of such a plant dies because food supply from leaves is cut off.
