Perianth occurs in family

Options

A. Solanaceae
B. Fabaceae
C. Brassicaceae
D. Liliaceae.

Answer

**Step-by-Step Solution:**

1. **Understanding Perianth**:
- Perianth is defined as the non-reproductive part of a flower, which includes two main components: the calyx (sepals) and the corolla (petals).

2. **Components of Perianth**:
- The calyx consists of sepals that protect the flower bud, while the corolla consists of petals that attract pollinators. Together, they form an envelope around the flower's reproductive organs.

3. **Identifying the Family**:
- The question asks in which family the perianth occurs. The options provided are Solanaceae, Fabaceae, Brassicaceae, and Liliaceae.

4. **Analyzing the Options**:
- **Solanaceae**: Known for having distinct petals and sepals but does not typically emphasize the perianth structure.
- **Fabaceae**: Generally has a more complex floral structure with a focus on reproductive parts rather than a prominent perianth.
- **Brassicaceae**: Has a characteristic flower structure but does not highlight the perianth as a key feature.
- **Liliaceae**: This family is known for its flowers that have a well-defined perianth.

5. **Characteristics of Perianth in Liliaceae**:
- In the Liliaceae family, the perianth is typically composed of six parts arranged in two whorls of three.
- These parts can be either scarious (thin and dry) or membranous (soft and flexible).

6. **Conclusion**:
- Based on the analysis, the perianth is most prominently featured in the Liliaceae family. Therefore, the correct answer is **Liliaceae**.

**Final Answer**: Liliaceae
