Multicellular branched rhizoids and leafy gametophytes are the characteristics of

Options

A. Some bryophytes
B. Pteridophytes
C. All bryophytes
D. Gymnosperms

Answer

To solve the question regarding the characteristics of multicellular branched rhizoids and leafy gametophytes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics**: The question mentions two specific characteristics: multicellular branched rhizoids and leafy gametophytes.

2. **Understand Rhizoids**: Rhizoids are root-like structures in non-vascular plants that help anchor the plant to the substrate. Multicellular and branched rhizoids indicate a more complex structure than simple rhizoids.

3. **Identify the Plant Groups**: We need to consider different groups of plants:
- **Bryophytes**: This group includes mosses, liverworts, and hornworts. They typically have gametophyte-dominant life cycles.
- **Pteridophytes**: This group includes ferns and their relatives, which have a dominant sporophyte generation and do not have rhizoids.
- **Gymnosperms**: These are seed-producing plants that do not have rhizoids and have a dominant sporophyte generation.
- **Angiosperms**: Flowering plants that also do not have rhizoids.

4. **Evaluate Each Group**:
- **Bryophytes**: Some bryophytes, such as Funaria and Sphagnum, exhibit multicellular branched rhizoids and leafy gametophytes. This matches the characteristics given in the question.
- **Pteridophytes**: They do not have branched rhizoids and are primarily sporophyte-dominant, so this option is incorrect.
- **Gymnosperms**: They do not possess rhizoids and have a diploid sporophyte body, making this option incorrect.
- **All Bryophytes**: While some bryophytes have leafy gametophytes, not all of them have the specified rhizoid characteristics, so this option is also incorrect.

5. **Conclusion**: The correct answer is that multicellular branched rhizoids and leafy gametophytes are characteristics of some bryophytes.

### Final Answer:
The characteristics of multicellular branched rhizoids and leafy gametophytes are found in **some bryophytes**.
