Which one is not a trait of xerophytes:

Options

A. Thick cuticle
B. Well developed mechanical tissue
C. Well developed conducting tissues
D. Spongy parenchyma.

Answer

To determine which trait is not associated with xerophytes, we can analyze the options provided:

1. **Thick Cuticle**: Xerophytes typically have a thick cuticle. This adaptation helps reduce water loss by minimizing transpiration, which is essential for survival in arid environments.

2. **Well-Developed Mechanical Tissue**: Xerophytes also possess well-developed mechanical tissues. These tissues provide structural support to withstand harsh conditions, such as strong winds and the weight of water storage.

3. **Well-Developed Conducting Tissues**: Xerophytes have well-developed conducting tissues, including xylem and phloem. Xylem is responsible for water transport, while phloem transports nutrients. This adaptation is crucial for their survival in environments where water is scarce.

4. **Spongy Parenchyma**: Spongy parenchyma is typically found in mesophytes and is involved in gas exchange and storage of substances. In xerophytes, the presence of spongy parenchyma is minimal or absent because these plants have adapted to conserve water and do not require extensive gas exchange.

Based on this analysis, the trait that is not characteristic of xerophytes is:

**Answer**: Spongy parenchyma (Option 4).
