Answer

To answer the question "When petals are green, the term used is:", we need to analyze the options provided and understand the terminology related to flower morphology.

### Step-by-Step Solution:

1. **Understanding Flower Parts**:
- Flowers consist of various parts, primarily petals and sepals.
- Petals are typically colorful and attract pollinators, while sepals are usually green and protect the flower bud.

2. **Identifying the Condition**:
- The question specifies a condition where petals are green. This is not typical, as petals are usually brightly colored.

3. **Analyzing the Options**:
- **Petaloid**: This term refers to structures that resemble petals but are not true petals. It does not apply here since we are discussing green petals.
- **Sepaloid**: This term refers to petals that resemble sepals. Since the petals are green, they are taking on characteristics of sepals.
- **Coralloid**: This term is not relevant to petals or sepals; it refers to a type of root structure in certain plants.
- **Haploid**: This term relates to the number of chromosomes and does not pertain to flower morphology.

4. **Conclusion**:
- Given that the petals are green and resemble sepals, the correct term to describe this condition is **sepaloid**.

### Final Answer:
When petals are green, the term used is **sepaloid**.
