S.G. Nawaschin (1898) discovered double fertilization in which of the following plants ?

Options

A. Fritillaria
B. Lilium
C. Both (1) and (2)
D. Arceuthobium

Answer

**Step-by-Step Solution:**

1. **Understanding Double Fertilization**:
- Double fertilization is a unique process observed in angiospermic plants where two fertilization events occur. One male gamete fuses with the egg cell to form the zygote, while the other fuses with two polar nuclei to form the endosperm.

2. **Identifying the Discoverer**:
- The biologist who first discovered double fertilization was S.G. Nawaschin in the year 1898.

3. **Plants Studied by Nawaschin**:
- Nawaschin conducted his research on two specific plants: Fritillaria and Lilium. He observed that double fertilization occurs in both of these plants.

4. **Evaluating the Options**:
- The options provided are:
- Fritillaria
- Lilium
- Both 1 and 2
- Arqueothobium
- Since both Fritillaria and Lilium are known to exhibit double fertilization, the correct answer would be "Both 1 and 2".

5. **Conclusion**:
- Therefore, the answer to the question is that S.G. Nawaschin discovered double fertilization in both Fritillaria and Lilium.

**Final Answer**: Both 1 and 2 (Fritillaria and Lilium).
