In some plants, anthers and stigma grow and mature at the same time. This phenomenon is called

Options

A. Homogamy
B. Syngamy
C. Allogamy
D. Fusion

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the phenomenon where anthers and stigma of a flower grow and mature simultaneously.

2. **Identifying the Type of Flower**: This phenomenon occurs in bisexual flowers, which contain both male (anthers) and female (stigma) reproductive parts.

3. **Defining the Terms**:
- **Anthers**: The part of the stamen that produces pollen.
- **Stigma**: The part of the pistil that receives pollen.

4. **Understanding Pollination**: In bisexual flowers, pollination can occur through:
- **Self-pollination (Autogamy)**: Pollen from the anther of the same flower fertilizes the stigma.
- **Indirect Autogamy**: Pollen reaches the stigma through agents like wind, insects, or gravity.

5. **Identifying the Specific Condition**: When both the anthers and stigma mature at the same time, it is referred to as **homogamy**.

6. **Evaluating the Options**:
- **Homogamy**: Correct answer, as it describes the simultaneous maturation of anthers and stigma.
- **Syngamy**: Incorrect, refers to the fusion of two gametes.
- **Allogamy**: Incorrect, refers to fertilization by pollen from another flower.
- **Fusion**: Incorrect, a general term for merging cells.

7. **Conclusion**: The correct answer is **homogamy**, which indicates the condition where anthers and stigma mature at the same time in bisexual flowers.
