The roots without root hairs, the stem without interno dal elongation and the compound leaf without rachis are respectively found in

Options

A. Cuscuta, Allium, Bombax
B. Rafflesia, Solanum, Neem
C. Rhizophora, Colocasia, Neem
D. Arachis, Lilium, Bombax

Answer

To solve the question regarding the plants with specific morphological characteristics, we will analyze each of the given traits step by step.

### Step-by-Step Solution:

1. **Identify the Traits**:
- The question mentions three specific traits:
- Roots without root hairs
- Stem without internal elongation
- Compound leaf without rachis

2. **Analyze Each Trait**:
- **Roots without root hairs**: This trait is commonly found in parasitic plants. One well-known example is **Cuscuta**, which is a complete parasite that lacks root hairs because it derives nutrients from the host plant.

- **Stem without internal elongation**: This trait is typically seen in plants that have modified stems. **Allium** (such as onion) has a fleshy stem that does not exhibit significant internal elongation, as it is adapted for storage.

- **Compound leaf without rachis**: A compound leaf without a rachis is usually a palmately compound leaf. **Bombax** (cotton tree) is an example of a plant that has palmately compound leaves, which do not have a distinct rachis.

3. **Match the Traits to the Plants**:
- From the analysis:
- Cuscuta corresponds to roots without root hairs.
- Allium corresponds to the stem without internal elongation.
- Bombax corresponds to the compound leaf without rachis.

4. **Conclusion**:
- Therefore, the plants that exhibit the specified traits are **Cuscuta**, **Allium**, and **Bombax**.

### Final Answer:
The roots without root hairs, the stem without internal elongation, and the compound leaf without rachis are respectively found in **Cuscuta, Allium, and Bombax**.
