Which of the following plants do not produce seeds?

Options

A. Ficus and Funaria
B. Fern and Funaria
C. Chlamydomonas and Ficus
D. Pumica and Pinus

Answer

To determine which plants do not produce seeds, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Plant Classification**:
- Plants are classified into different groups based on their reproductive structures. The main groups include seed-producing plants (like angiosperms and gymnosperms) and non-seed producing plants (like bryophytes and pteridophytes).

2. **Identify Non-Seed Producing Groups**:
- **Bryophytes**: This group includes mosses and liverworts. They reproduce via spores and do not produce seeds.
- **Pteridophytes**: This group includes ferns. They also reproduce via spores and do not produce seeds.

3. **Analyze the Options Provided**:
- **Ficus**: This is a flowering plant (angiosperm) that produces seeds, so it does not belong to the non-seed producing category.
- **Finaria**: This is a type of moss, which is a bryophyte and does not produce seeds.
- **Fern**: This is a pteridophyte and also does not produce seeds.
- **Chlamydomonas**: This is an algae and does not produce seeds, but it is not a plant in the traditional sense.
- **Pumicea and Pinus**: These belong to the gymnosperms, which produce seeds (though they are naked seeds).

4. **Conclusion**:
- The plants that do not produce seeds from the options given are **fern** and **finaria** (moss).

### Final Answer:
The plants that do not produce seeds are **fern and finaria**.
