Which of the following plant traits (characters) is NOT an adaptatioin to dry (Xeric) habitats?

Options

A. Sunken stomata on leaves
B. Highly developed root system
C. Thin epidermis without a cuticle on stem and leaves
D. Small leaves and photosynthetic stem

Explanation

To determine which plant trait is NOT an adaptation to dry (xeric) habitats, we need to analyze the characteristics of plants that thrive in such environments.

1. **Sunken Stomata on Leaves**:
- In xeric habitats, plants often have sunken stomata to reduce water loss through transpiration. This adaptation helps in conserving moisture.
- **Conclusion**: This trait IS an adaptation to dry habitats.

2. **Highly Developed Root System**:
- Plants in dry environments typically have extensive root systems to access water from deeper soil layers. This adaptation is crucial for survival in arid conditions.
- **Conclusion**: This trait IS an adaptation to dry habitats.

3. **Epidermis Without a Cuticle on Stem and Leaf**:
- In xeric conditions, plants usually have a thick cuticle on their leaves and stems to minimize water loss. A lack of a cuticle would lead to increased transpiration and water loss, which is detrimental in dry environments.
- **Conclusion**: This trait is NOT an adaptation to dry habitats.

4. **Small Leaves and Photosynthetic Stem**:
- Smaller leaves reduce the surface area for transpiration, and a photosynthetic stem allows the plant to perform photosynthesis while minimizing water loss. This is an effective adaptation for survival in dry conditions.
- **Conclusion**: This trait IS an adaptation to dry habitats.

Based on the analysis above, the trait that is NOT an adaptation to dry (xeric) habitats is **"Epidermis Without a Cuticle on Stem and Leaf."**
