Smooth and pegged rhizoids are present in the gametophyte of

Options

A. Bryopsida
B. Pteropsida
C. Anthoceropsida
D. Hepaticopsida.

Answer

To answer the question regarding the presence of smooth and pegged rhizoids in the gametophyte, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Rhizoids**: Rhizoids are root-like structures found in non-vascular plants that help anchor the plant to the substrate. They can be classified into different types based on their structure.

2. **Identifying the Types of Rhizoids**: In the context of the question, we need to focus on two types of rhizoids:
- **Smooth Rhizoids**: These are characterized by a smooth surface.
- **Pegged Rhizoids (also known as Tuberculate Rhizoids)**: These have a more textured surface, often described as having tubercles or bumps.

3. **Reviewing the Options**: The question provides four options:
- Option 1: Bryopsida
- Option 2: Cheropsida
- Option 3: Anthoceropsida
- Option 4: Hepaticopsida

4. **Analyzing Hepaticopsida**: The class Hepaticopsida, commonly known as liverworts, is known for having a dominant gametophyte that can exhibit both smooth and pegged rhizoids. The gametophyte can be either thallus or foliage-like in structure.

5. **Conclusion**: Based on the characteristics of the rhizoids and the classification of the plants, the correct answer is **Option 4: Hepaticopsida**. This class includes plants that have both smooth and pegged rhizoids in their gametophyte stage.

### Final Answer:
Smooth and pegged rhizoids are present in the gametophyte of **Hepaticopsida**.
