Question

“Girdling Experiment” was performed by plant physiologists to identify the plant tissue through which:

• A. Water is transported
• B. Food is transported
• C. For both water and food transportation
• D. Osmosis is observed

Answer 1

The Correct Option is B

The "Girdling Experiment" is a classic experiment used to understand the role of different plant tissues in the transportation process. Through this experiment, plant physiologists can identify the specific tissue responsible for transporting food within the plant. The process involves removing a ring of bark from around the circumference of a stem or tree, which includes the phloem layer but leaves the xylem intact.

• Phloem Removal: By girdling a plant, the phloem, which normally carries sugars and other organic nutrients, is disrupted.
• Observation: After girdling, if the transport of food (sugars) stops above the girdled point, this indicates that the phloem is responsible for this transportation.
• Conclusion: The experiment confirms that the tissue involved in transporting food in plants is the phloem. This is because, after girdling, you can observe accumulation of sugar solutions above the girdle and depletion below, which aligns with the interrupted downward transport in the phloem.

Thus, the correct answer is: Food is transported.
