Non-vascular embryophyte with leaves is

Options

A. Riccia
B. Porella
C. Selaginella
D. Macrocystis

Answer

To solve the question "Non-vascular embryophyte with leaves is," we will analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question asks for a non-vascular embryophyte that has leaves. Non-vascular plants are those that do not have specialized tissues (xylem and phloem) for transporting water and nutrients.

2. **Identifying the Options**:
- **Option A: Hia** - We need to check if this is a non-vascular plant and if it has leaves.
- **Option B: Porella** - We need to check if this is a non-vascular plant and if it has leaves.
- **Option C: Selaginella** - We need to check if this is a non-vascular plant and if it has leaves.
- **Option D: Macrocystis** - We need to check if this is a non-vascular plant and if it has leaves.

3. **Analyzing Each Option**:
- **Macrocystis**: This is a type of brown algae. It has vascular tissues, so it does not qualify as a non-vascular plant. Therefore, it can be eliminated.
- **Selaginella**: This belongs to the group of pteridophytes, which are vascular plants. Thus, it can also be eliminated.
- **Hia**: This option is not commonly recognized in the context of non-vascular plants, and further research would be needed to confirm its classification. However, it is likely not the answer.
- **Porella**: This is a liverwort, which is a type of bryophyte. Bryophytes are non-vascular plants, and Porella has well-developed leaves.

4. **Conclusion**:
- After analyzing all the options, the only non-vascular embryophyte that has leaves is **Porella**. Therefore, the correct answer is **Option B: Porella**.

### Final Answer:
**Option B: Porella**
