Tendrils in plants are an example of

Options

A. convergent evolution
B. radiation
C. divergent evolution
D. co-evolution

Answer

**Step-by-Step Solution:**

1. **Understanding Tendrils**:
- Tendrils are specialized structures in plants that are typically modified stems or leaves. Their primary function is to help support the plant by wrapping around objects.

2. **Identifying the Type of Evolution**:
- To determine the type of evolution represented by tendrils, we need to consider their relationship with other structures in plants, such as thorns.

3. **Homologous Structures**:
- Tendrils and thorns are examples of homologous structures. This means that they share a common origin (both originate from axillary buds) but have different functions (tendrils support the plant, while thorns provide protection).

4. **Divergent Evolution**:
- The concept of divergent evolution refers to the process where two or more related species become more dissimilar over time, often due to different environmental pressures or functions. Since tendrils and thorns have the same origin but different functions, they exemplify divergent evolution.

5. **Conclusion**:
- Therefore, the correct answer to the question "Tendrils in plants are an example of" is **divergent evolution** (Option 3).
