Double fertilization was discovered by:

Options

A. Hofmeister
B. Strasburger
C. Nawaschin
D. Amici

Answer

**Step-by-Step Solution:**

1. **Understanding Double Fertilization**: Double fertilization is a unique process that occurs in angiosperms (flowering plants) where two fertilization events take place. One male gamete fuses with the egg cell to form a zygote, while the other male gamete fuses with two polar nuclei to form the triploid endosperm.

2. **Identifying the Key Components**: In double fertilization, we have:
- **Syngamy**: The fusion of one male gamete with the female gamete (egg) to form a zygote.
- **Triple Fusion**: The fusion of the second male gamete with the central cell (which contains two polar nuclei) to form the endosperm.

3. **Historical Context**: The discovery of double fertilization is attributed to a specific scientist. It is important to know who made this significant contribution to the field of botany.

4. **Identifying the Scientist**: The scientist who discovered double fertilization is **Nawaschin**. He conducted research that led to the understanding of this process in angiosperms.

5. **Eliminating Other Options**: The other scientists mentioned (Hofmeister, Strasburger, and Amici) are not credited with the discovery of double fertilization. Thus, they can be eliminated as possible answers.

6. **Conclusion**: Based on the information gathered, the correct answer to the question "Double fertilization was discovered by:" is **Nawaschin**.

**Final Answer**: Nawaschin
