Triple fusion is also known as

Options

A. Trophomixis
B. Amphimixis
C. Endomixis
D. Hemimixis

Answer

**Step-by-Step Solution:**

1. **Understanding Triple Fusion**: Triple fusion is a process that occurs in angiosperms (flowering plants). It involves the fusion of one male gamete with two polar nuclei within the embryo sac.

2. **Identifying the Components**: In the process of triple fusion, the male gamete is derived from the pollen grain. The two polar nuclei are located inside the embryo sac, which is found within the ovule.

3. **Formation of Endosperm**: The result of triple fusion is the formation of endosperm, which serves as a nutritive tissue for the developing embryo. The endosperm is triploid (3n) because it is formed from the fusion of one haploid male gamete (1n) with two haploid polar nuclei (1n + 1n).

4. **Choosing the Correct Term**: The question asks for an alternative name for triple fusion. The options provided are:
- Trophomixes
- Amphimixes
- Endomixes
- Hemimixes

5. **Eliminating Incorrect Options**:
- **Amphimixes** refers to the fusion of gametes to form a zygote, which is not the same as triple fusion.
- **Endomixis** pertains to nuclear reorganization in certain protozoans, which is unrelated to the process in angiosperms.
- **Hemimixes** involves the reconstruction of the macronucleus, which is also not relevant to triple fusion.

6. **Conclusion**: The correct answer is **Trophomixes**, which is the term used to describe triple fusion in angiosperms.

**Final Answer**: Triple fusion is also known as **Trophomixes**.
