Trabecullae are present in the

Options

A. Capsule of Funaria
B. Ovule of gymnosperm
C. Sporangia of a fern
D. Ovule of angiosperm

Answer

**Step-by-Step Solution:**

1. **Understanding Trabeculae**: Trabeculae are defined as plates of cells that are found across the cavity of the sporangium in mosses. This is a key characteristic that helps identify their presence.

2. **Analyzing the Options**: The question provides four options:
- Capsule of Funerea
- Ovule of Gymnosperm
- Sporangia of a Fern
- Ovule of Angiosperm

3. **Evaluating Each Option**:
- **Capsule of Funerea**: Funerea is a type of moss. Since trabeculae are characteristic of mosses, this option is likely correct.
- **Ovule of Gymnosperm**: Gymnosperms are not mosses, so trabeculae would not be present here. This option is incorrect.
- **Sporangia of a Fern**: Ferns belong to the group of plants known as pteridophytes, which are also not mosses. Therefore, this option is incorrect.
- **Ovule of Angiosperm**: Angiosperms are flowering plants and are also not mosses. Thus, this option is incorrect.

4. **Conclusion**: After evaluating all options, the only correct answer is the **Capsule of Funerea**, as it is the only option that pertains to mosses where trabeculae are present.

5. **Internal Structure of the Capsule**: The capsule of Funerea is differentiated into three regions: the apophysis, theca, and operculum. In the thicker region, there is a wide airspace that is traversed by transverse strands known as trabeculae, which connect the capsule wall with the wall of the spore sac.

**Final Answer**: Trabeculae are present in the **Capsule of Funerea**.
