A simple experiment called is used to identify the tissues through which food is transported.

Options

A. layering
B. reverse osmosis
C. girdling
D. grafting

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for a simple experiment that identifies the tissue responsible for food transport in plants.

2. **Identifying the Experiment:**
The experiment referred to is known as the "Kittling Experiment." This experiment is specifically designed to demonstrate the role of a particular tissue in the transport of food.

3. **Conducting the Experiment:**
In the Kittling Experiment, a ring of bark is removed from the trunk of a tree. This removal is done carefully to reach the depth of the phloem tissue, which is the tissue responsible for transporting food.

4. **Observing the Results:**
After the phloem is removed, food substances begin to accumulate above the ring where the bark was removed. This accumulation occurs because the phloem, which normally transports food downwards, has been disrupted.

5. **Analyzing the Outcome:**
The accumulation of food substances leads to swelling in the upper portion of the trunk. This swelling indicates that the phloem is indeed responsible for the transport of food, as its removal prevents the downward movement of food.

6. **Conclusion:**
From the results of the Kittling Experiment, it is concluded that the phloem tissue is the one responsible for the translocation of food in plants. Thus, the correct answer to the question is the Kittling Experiment.

**Final Answer:**
The simple experiment used to identify the tissues through which food is transported is called the Kittling Experiment.
