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, let's analyze each option step by step.

### Step 1: Understanding Bryophytes
Bryophytes are non-vascular plants that include mosses and liverworts. They are often referred to as the amphibians of the plant kingdom because they require water for fertilization.

### Step 2: Evaluating Each Statement

1. **Option 1: In bryophytes, zygote does not undergo reductional division immediately.**
- This statement is **true**. In bryophytes, the zygote develops into a multicellular structure called the sporophyte before undergoing meiosis to produce haploid spores.

2. **Option 2: Leafy members having leaf-like appendages in two rows on the stem-like structures are not observed in liverworts.**
- This statement is **false**. Liverworts do have leafy structures, and they can exhibit leaf-like appendages, so this option is incorrect.

3. **Option 3: Leafy stage of mosses develops from the primary protonema as a lateral bud.**
- This statement is **false**. The leafy stage of mosses develops from the secondary protonema, not the primary protonema. Therefore, this option is incorrect.

4. **Option 4: The sporophyte of mosses is less elaborate than that of liverworts.**
- This statement is **false**. The sporophyte of mosses is generally more complex and elaborate compared to that of liverworts.

### Conclusion
After evaluating all the options, the only true statement about bryophytes is **Option 1: In bryophytes, zygote does not undergo reductional division immediately.**

### Summary of Steps:
1. Understand the characteristics of bryophytes.
2. Analyze each statement for accuracy based on biological principles.
3. Identify the true statement.
