Lever mechanism or turn pipe machanism of pollination is found in

Options

A. Antirrinum
B. Ficus
C. salvia
D. homogamy

Answer

To solve the question regarding which plant exhibits the lever mechanism or turnpipe mechanism of pollination, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Mechanism**: The lever mechanism or turnpipe mechanism of pollination refers to a specific way in which flowers utilize their structure to facilitate the transfer of pollen. This often involves the movement of parts of the flower that act like levers to aid in pollination.

2. **Identify the Options**: The question provides four options:
- A. T. renum
- B. Ficus
- C. Salvia
- D. Homogen

3. **Research Each Option**:
- **T. renum**: Typically known for its unique reproductive strategies, but not specifically associated with the lever mechanism.
- **Ficus**: Generally relies on fig wasps for pollination and does not exhibit the lever mechanism.
- **Salvia**: Known for its unique structure that facilitates insect pollination through a lever mechanism, where the flower's parts move to effectively transfer pollen to visiting insects.
- **Homogen**: This option is less commonly known and does not typically relate to the lever mechanism.

4. **Conclusion**: Based on the characteristics of the plants and their pollination mechanisms, **Salvia** is the correct answer. It employs the lever mechanism or turnpipe mechanism to assist in the pollination process by utilizing insects.

5. **Final Answer**: The lever mechanism or turnpipe mechanism of pollination is found in **Salvia**.
