Self-incompatibility is found in flowers of plants…..

Options

A. Calotropis
B. maize
C. Thea
D. Gloriosa

Answer

### Step-by-Step Solution:

1. **Understanding Self-Incompatibility**:
- Self-incompatibility is a biological mechanism in plants that prevents self-fertilization. This means that the male and female reproductive parts of the same flower cannot fertilize each other.

2. **Identifying the Process**:
- In self-incompatible plants, the timing of maturation of the stigma (female part) and anther (male part) is different. This difference ensures that pollen from the same flower cannot fertilize its own ovules.

3. **Analyzing the Given Options**:
- The question provides four plant options. We need to determine which of these exhibits self-incompatibility.

4. **Evaluating Each Option**:
- **Seed Plant**: This plant shows different maturation times for stigma and anther, promoting cross-pollination. This is indicative of self-incompatibility.
- **Callotropy**: This plant allows for self-pollination, meaning it does not exhibit self-incompatibility.
- **Maze**: Similar to Callotropy, this plant also allows self-pollination.
- **Gloriosa**: Like the previous two, Gloriosa can also self-pollinate.

5. **Conclusion**:
- Among the options, the only plant that demonstrates self-incompatibility is the Seed Plant. Therefore, the correct answer is the Seed Plant.

### Final Answer:
Self-incompatibility is found in the flowers of the Seed Plant.
