The carrying of male gametes near female gametes by pollen tube is called

Options

A. Porogamy
B. Chalazogamy
C. Siphonogamy
D. Mesogamy.

Answer

To solve the question regarding the carrying of male gametes near female gametes by the pollen tube, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Components**:
- Identify the male and female gametes in plants. The male gametes are represented by pollen grains, while the female gametes are found in the ovule, specifically in the embryo sac.

2. **Role of Pollen Tube**:
- Recognize that the pollen tube is a structure that forms after pollination. Its primary function is to transport male gametes (sperm cells) from the pollen grains to the female gametes (egg cells) in the ovule.

3. **Types of Fertilization**:
- Familiarize yourself with the different types of fertilization processes:
- **Porogamy**: Pollen tube enters through the micropylar end of the ovule.
- **Chalazogamy**: Pollen tube enters through the chalaza end of the ovule.
- **Mesogamy**: Pollen tube enters through the integuments.
- **Cephanogamy**: This term specifically refers to the process where the pollen tube carries male gametes to the female gametes.

4. **Identifying the Correct Term**:
- From the definitions above, note that the question specifically asks for the process of carrying male gametes to female gametes by the pollen tube. The correct term for this process is **Cephanogamy**.

5. **Conclusion**:
- Therefore, the answer to the question is **Cephanogamy**, as it accurately describes the carrying of male gametes near female gametes by the pollen tube.

### Final Answer:
**Cephanogamy**
