The sporophyte of mosses is:-

Options

A. Parasite
B. Semiparasite
C. Free living
D. Differentiated in root, stem and leaves

Answer

**Step-by-Step Solution:**

1. **Understanding Sporophyte in Mosses**: The sporophyte is the diploid generation in the life cycle of mosses, which develops from the fertilized egg (zygote) and is dependent on the gametophyte for nutrition.

2. **Structure of the Sporophyte**: The sporophyte of mosses consists of three main parts:
- **Seta**: A stalk-like structure that connects the sporangium (capsule) to the gametophyte.
- **Capsule**: The part where spores are produced and stored.
- **Foot**: The base that anchors the sporophyte to the gametophyte and absorbs nutrients.

3. **Nutritional Dependency**: The sporophyte is not fully independent; it relies on the gametophyte for water and nutrients, indicating a semi-parasitic nature.

4. **Photosynthesis**: While the sporophyte can perform photosynthesis to some extent, it primarily depends on the gametophyte for sustenance.

5. **Conclusion**: Based on its characteristics and dependency, the correct classification of the sporophyte of mosses is that it is semi-parasitic.

**Final Answer**: The sporophyte of mosses is semi-parasitic (Option 2).
