Which of these statement about bryophytes is true?

Options

A. In bryophytes , zygote dose not undergo reduction division immediately.
B. Leafy members having leaf-like appendages in two rows on the stem-like structures are not observed in liverworts .
C. Leafy stage of mosses develops from the primary protonema as a lateral bud .
D. The sporophyte of mosses is less elaborate than that of liverworts .

Answer

To determine which statement about bryophytes is true, we will analyze the characteristics and reproductive processes of bryophytes, particularly focusing on their structure and life cycle.

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They are often referred to as the amphibians of the plant kingdom because they require water for their reproductive processes.

**Hint**: Remember that bryophytes are non-vascular and rely on water for reproduction.

2. **Analyzing the Statements**:
- **Statement 1**: "In bryophytes, zygote does not undergo reduction division immediately."
- This statement is true. After fertilization, the zygote develops into a multicellular sporophyte, which eventually undergoes meiosis to produce haploid spores.

**Hint**: Focus on the zygote's development in bryophytes and its role in the life cycle.

3. **Evaluating Other Statements**:
- **Statement 2**: "Leafy members having leaf-like appendices in two rows on the stem-like structures are not observed in liverworts."
- This is false. Liverworts can have leaf-like structures, and this description fits some liverworts.

**Hint**: Consider the morphological characteristics of liverworts and mosses.

- **Statement 3**: "Leafy stages of mosses developed from the primary protonema as a lateral bud."
- This is incorrect. The leafy stage of mosses develops from the secondary protonema, not the primary.

**Hint**: Recall the stages of moss development and the role of protonema.

- **Statement 4**: "The sporophyte of moss is less elaborate than that of liverworts."
- This is also false. The sporophyte of mosses is typically more complex and elaborate compared to that of liverworts.

**Hint**: Compare the structure of sporophytes in mosses and liverworts.

4. **Conclusion**:
- The only true statement about bryophytes is that "In bryophytes, zygote does not undergo reduction division immediately." Therefore, the correct answer is **Statement 1**.

### Final Answer:
The true statement about bryophytes is: "In bryophytes, zygote does not undergo reduction division immediately."
