What kind of modification for propagation is seen in ginger and banana ?

Options

A. Modification of tap root for food storage
B. Modification of adventitious root for food storage
C. Modification of stem for food storage
D. Zaminkand as modification of root and turmericas modified stem

Answer

To answer the question about the kind of modification for propagation seen in ginger and banana, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Identify the Plants**: Recognize that the question is asking about ginger and banana, which are both known for their unique structures that aid in propagation.

2. **Understand the Structures**:
- **Ginger**: Ginger is known for its underground stem called a rhizome.
- **Banana**: Similarly, bananas also propagate through rhizomes.

3. **Define Rhizome**: A rhizome is a type of modified stem that grows horizontally underground. It serves as a storage organ and a means of vegetative reproduction.

4. **Function of Rhizomes**: In both ginger and banana, the rhizome acts as a food storage structure, storing nutrients such as starch and proteins. This allows the plant to survive adverse conditions and aids in the growth of new shoots.

5. **Evaluate the Options**:
- **Modification of tap root for food storage**: This is incorrect as it pertains to plants like carrots and turnips.
- **Modification of adventitious root for food storage**: This is incorrect as it relates to plants like sweet potatoes.
- **Modification of stem for food storage**: This is correct as it refers to the rhizomes in ginger and banana.
- **Zamecans as modification of root and turmeric as modified stem**: This is also incorrect.

6. **Conclusion**: The correct answer is that ginger and banana exhibit a modification of stem for food storage, specifically through their rhizomes.

### Final Answer:
The kind of modification for propagation seen in ginger and banana is the modification of stem for food storage (rhizome).
