Which of the following options shows two plants in which new plantlets arise from the same organ ?

Options

A. Dahlia and ginger
B. Potato and sweet potato
C. Dahlia and rose
D. Potato and sugarcane

Explanation

To solve the question, "Which of the following options shows two plants in which new plantlets arise from the same organ?", we will analyze the options provided and determine which pairs of plants reproduce in this manner.

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify two plants that produce new plantlets from the same organ.

2. **Analyze the Options**:
- **Option 1: Dahlia and Ginger**
- **Dahlia**: Dahlia reproduces through vegetative propagation, primarily from its stem. New plants arise from cuttings of the stem, not from the same organ.
- **Ginger**: Ginger reproduces from its rhizome (a modified stem), where new shoots can emerge. This means new plantlets arise from the same organ (the rhizome).
- **Conclusion**: This pair does not satisfy the condition since Dahlia does not produce plantlets from the same organ.

3. **Option 2: Potato and Sweet Potato**
- **Potato**: Potatoes reproduce through tubers, specifically from the "eyes" of the potato, which are buds that can grow into new plants. This is from the same organ (the tuber).
- **Sweet Potato**: Sweet potatoes reproduce from the stem, not from the tuber itself.
- **Conclusion**: This pair does not satisfy the condition since sweet potato does not produce plantlets from the same organ.

4. **Option 3: Dahlia and Rose**
- **Dahlia**: As previously mentioned, Dahlia reproduces from its stem.
- **Rose**: Roses also reproduce through stem cuttings.
- **Conclusion**: This pair does not satisfy the condition since both plants reproduce from their stems, but they do not share the same organ.

5. **Option 4: Potato and Sugarcane**
- **Potato**: As mentioned, potatoes reproduce from the tuber (the same organ).
- **Sugarcane**: Sugarcane reproduces from its nodes, where buds are present. When a segment of sugarcane with a bud is planted, it can grow into a new plant. This means new plantlets arise from the same organ (the stem).
- **Conclusion**: This pair satisfies the condition since both plants produce new plantlets from the same organ.

6. **Final Answer**: The correct option is **Potato and Sugarcane**.
