In thallophyta main plant body is :-

Options

A. Gametophyte
B. Sporophyte
C. Diploid plant body
D. Leafy plant body

Answer

To answer the question "In thallophyta, the main plant body is:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Thallophyta**:
- Thallophyta is a group of simple plants that includes algae, fungi, and lichens. They are characterized by the absence of true roots, stems, and leaves.

2. **Identifying Plant Body Types**:
- The main types of plant bodies are:
- **Gametophyte**: The haploid phase that produces gametes.
- **Sporophyte**: The diploid phase that produces spores.
- **Diploid Plant Body**: Refers to a plant body with two sets of chromosomes (2N).
- **Leafy Plant Body**: A structure that has differentiated leaves.

3. **Characteristics of Thallophyta**:
- In thallophyta, the plant body is not differentiated into roots, stems, and leaves. Instead, it is a simple structure known as a thallus.

4. **Reproductive Structures**:
- The reproductive parts of thallophytes are often unicellular and are involved in the production of gametes.

5. **Conclusion**:
- Since thallophyta primarily consists of a gametophyte structure that generates gametes, the main plant body in thallophyta is a **gametophyte**.

### Final Answer:
The main plant body in thallophyta is **gametophyte**.
