in which of the following plants, triple fusion and double fertillization was discovered?

Options

A. Portulaca & Cucurbit
B. Lillium & Fritillaria
C. Triticum & Lily
D. Fritillaria & Colocasia

Answer

To solve the question regarding which plants were used to discover triple fusion and double fertilization, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concepts**:
- **Double Fertilization**: This is a unique process in angiosperms where one sperm fertilizes the egg to form the zygote, and the other sperm fuses with two polar nuclei to form the triploid endosperm.
- **Triple Fusion**: This refers specifically to the fusion of one sperm cell with two polar nuclei, resulting in the formation of the triploid endosperm.

2. **Identify the Scientists**:
- The discovery of double fertilization and triple fusion was made by two scientists: **Navastim** and **Gignard**.

3. **Determine the Plant Species**:
- The two plant species where these processes were studied and discovered are **Fritillaria** and **Lilium**.

4. **Conclusion**:
- Based on the information gathered, the answer to the question is that triple fusion and double fertilization were discovered in the plants **Fritillaria** and **Lilium**.

5. **Select the Correct Option**:
- Therefore, the correct option is **B** (Fritillaria and Lilium).

### Final Answer:
The plants in which triple fusion and double fertilization were discovered are **Fritillaria and Lilium** (Option B).
