All given members are monoecious, except

Options

A. Marchantia
B. Funaria
C. Anthoceros
D. Sphagnum

Answer

To solve the question "All given members are monoecious, except," we need to analyze the reproductive characteristics of the given members: Marchantia, Funeria, Anthoceros, and Sphagnum.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Monoecious**: A plant species that has both male and female reproductive organs on the same individual.
- **Dioecious**: A plant species that has male and female reproductive organs on separate individuals.

2. **Analyze Each Option**:
- **Marchantia**: This is a liverwort and is known to be dioecious, meaning it has separate male and female plants.
- **Funeria**: This is a type of moss and is monoecious, meaning it has both male and female reproductive organs on the same plant.
- **Anthoceros**: Commonly known as hornworts, these are also monoecious.
- **Sphagnum**: Known as peat moss, this plant is also monoecious.

3. **Identify the Odd One Out**:
- From the analysis, Marchantia is the only member that is dioecious, while Funeria, Anthoceros, and Sphagnum are all monoecious.

4. **Conclusion**:
- Therefore, the correct answer to the question is Marchantia, as it is the only member that is not monoecious.

### Final Answer:
**Marchantia** is the member that is dioecious, while the others (Funeria, Anthoceros, and Sphagnum) are monoecious.
