Unique character of Thallophyta is :-

Options

A. Thalloid body
B. Absence of vascular tissue
C. Zygotic meiosis
D. All of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Thallophyta**: Thallophyta is a division of plants that includes organisms like algae, fungi, and lichens. These organisms are characterized by their simple body structure.

2. **Identifying Unique Characteristics**: The unique characteristics of Thallophyta include:
- **Thalloid Body**: Thallophytes do not have a differentiated plant body (roots, stems, leaves). Instead, they have a thallus, which is a simple body structure.
- **Absence of Vascular Tissue**: Thallophytes lack specialized vascular tissues such as xylem and phloem, which are responsible for the transport of water and nutrients in higher plants.
- **Zygotic Meiosis**: In Thallophyta, the zygote formed after fertilization undergoes meiosis to produce haploid spores. This process is known as zygotic meiosis.

3. **Conclusion**: Since all the mentioned characteristics (thalloid body, absence of vascular tissue, and zygotic meiosis) are unique to Thallophyta, the correct answer to the question is "all of the above."

**Final Answer**: The unique character of Thallophyta is all of the above.
