Answer

To solve the question regarding the features like needle-shaped leaves, thick cuticle, sunken stomata, and the development of male and female strobili on the same plant, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Features**: The question lists specific features:
- Needle-shaped leaves
- Thick cuticle
- Sunken stomata
- Development of male and female strobili on the same plant

2. **Understand Gymnosperms**: Recognize that the options provided (Pinus, Cycus, Ginkgo, and Ephedra) are all examples of gymnosperms, which are seed-producing plants with naked seeds.

3. **Analyze Each Option**:
- **Pinus**: This is a conifer that exhibits all the listed features: needle-shaped leaves, thick cuticle, sunken stomata, and both male and female strobili on the same plant.
- **Cycus**: In Cycus, male and female strobili are found on different plants, which does not meet the requirement.
- **Ginkgo**: Ginkgo has amphicyclic stomata, which are not sunken, thus it does not fulfill the criteria.
- **Ephedra**: Similar to Cycus, in Ephedra, male and female strobili are also on different plants, making it an incorrect choice.

4. **Conclusion**: Since only Pinus meets all the specified features, it is the correct answer.

### Final Answer:
The features like needle-shaped leaves, thick cuticle, sunken stomata, and development of male and female strobili on the same plant are present in **Pinus**.
