Rhizoid containing sporophytic plants are characteristic of:-

Options

A. Bryopsida
B. Spenopsida
C. Cycadophyta
D. Psilopsida

Answer

To solve the question regarding which group of sporophytic plants contains rhizoids, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Rhizoids**:
- Rhizoids are root-like structures found in certain plants that help anchor the plant and absorb water and nutrients.

2. **Identify the Groups of Plants**:
- The question refers to sporophytic plants, which are the diploid phase of the plant life cycle. The groups mentioned in the video transcript include Bryopsida, Sphenopsida, Cycadophyta, Psilopsida, and specifically Sialopsida.

3. **Characteristics of Sporophytic Plants**:
- In the context of the groups mentioned, we need to determine which of these groups is characterized by having rhizoids in their sporophyte stage.

4. **Focus on Sialopsida**:
- According to the transcript, Sialopsida is highlighted as the group that has rootless sporophytes. These plants have a differentiated underground rhizome and an aerial part that is diacotomously branched.

5. **Conclusion**:
- Based on the characteristics described, the correct answer to the question is **Sialopsida**. This group is characterized by the presence of rhizoids in their sporophyte stage.

### Final Answer:
**Sialopsida**
