Dispersal of seed in Opium Poppy/Argemone occurs by

Options

A. Explosive mechanism
B. Parachute mechanism
C. Censer mechanism
D. Jaculator mechanism

Answer

### Step-by-Step Solution:

1. **Understanding Seed Dispersal Mechanisms**:
- Seed dispersal can occur through various mechanisms, including explosive, parachute, sensor, and ejaculator mechanisms. Each mechanism has distinct characteristics.

2. **Explosive Mechanism**:
- In this mechanism, the pods burst open rapidly to release seeds. This is commonly observed in plants like pea. Therefore, this mechanism does not apply to Opium Poppy or Argemone.

3. **Parachute Mechanism**:
- This mechanism involves seeds being carried away by the wind, aided by parachute-like structures. This is typical in plants like maple trees. Hence, it is also not the correct mechanism for Opium Poppy or Argemone.

4. **Sensor Mechanism**:
- The sensor mechanism involves the shaking of fruits, often by wind, which causes seeds to be released in small clusters or aggregates. This mechanism is observed in the case of Opium Poppy and Argemone.

5. **Ejaculator Mechanism**:
- This mechanism involves hook-like structures that attach to animals, facilitating seed dispersal. This is seen in plants like Rovelia. Thus, it is not applicable to Opium Poppy or Argemone.

6. **Conclusion**:
- The correct mechanism for seed dispersal in Opium Poppy and Argemone is the sensor mechanism, where the fruit is shaken, leading to the release of seeds in clusters.

### Final Answer:
The dispersal of seeds in Opium Poppy and Argemone occurs by the **sensor mechanism**.
