Double fertilization was discovered by

Options

A. Nawaschin
B. Schleiden
C. Schwann
D. Mendel

Answer

**Step-by-Step Solution:**

1. **Understanding Double Fertilization**:
- Double fertilization is a unique process that occurs in angiosperms (flowering plants). It involves two fertilization events within the ovule.

2. **Process of Double Fertilization**:
- In this process, one male gamete (sperm cell) fuses with the egg cell to form a diploid zygote.
- Simultaneously, another male gamete fuses with two polar nuclei to form a triploid cell, which develops into the endosperm, providing nourishment to the developing embryo.

3. **Historical Context**:
- The discovery of double fertilization is significant in the study of plant reproduction and was first identified in the late 19th century.

4. **Identifying the Scientist**:
- The scientist credited with the discovery of double fertilization is **Nawaschin**. His work helped to elucidate this complex reproductive process in flowering plants.

5. **Conclusion**:
- Therefore, the correct answer to the question "Double fertilization was discovered by" is **Nawaschin**.
