Simplest and highly reduced archegonium is found in

Options

A. Pinus
B. Fern
C. Bryophytes
D. Liver worts/mosses

Answer

To solve the question regarding the simplest and highly reduced archegonium, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Archegonium**:
- Archegonium is the female reproductive organ in plants. It is typically flask-shaped and consists of a neck and a swollen base, known as the venter, which contains the egg.

2. **Identify the Options**:
- The options given are:
1. Pinus
2. Fern
3. Bryophytes
4. Liverworts

3. **Analyze Each Option**:
- **Pinus**: In Pinus (a gymnosperm), the structure does not have a traditional archegonium. Instead, it contains the egg directly without the surrounding archegonial structure.
- **Fern**: Ferns have well-defined archegonia that are more complex than that of Pinus.
- **Bryophytes**: Bryophytes, like mosses, have archegonia that are also more developed than that of Pinus.
- **Liverworts**: Liverworts have archegonia, but they are still more complex than the egg structure in Pinus.

4. **Conclusion**:
- Since Pinus does not have a traditional archegonium and contains only the egg, it represents the simplest and most reduced form of archegonium. Therefore, the correct answer is **Pinus**.

### Final Answer:
The simplest and highly reduced archegonium is found in **Pinus**.
