Which is not correct about Funaria.

Options

A. Sporophyte is semiparasite on gametophyte
B. Spores are produced by outer endothecial cells
C. The spore germinates to produces primary protonema
D. There are two neck canal cells in archegonia.

Answer

To determine which statement about Funaria is incorrect, we can analyze each option step by step:

### Step-by-Step Solution:

1. **Understanding Funaria**:
- Funaria is a genus of mosses, which are classified as bryophytes. Bryophytes are non-vascular plants that typically grow in moist environments.

2. **Evaluating Option A**:
- **Statement**: "A sporophyte is a semi-parasite on the gametophyte."
- **Analysis**: This statement is correct. The sporophyte of Funaria is dependent on the gametophyte for nutrition, which means it relies on the gametophyte for sustenance.

3. **Evaluating Option B**:
- **Statement**: "Spores are produced by the outer endothelial cell."
- **Analysis**: This statement is also correct. Spores in Funaria are produced in the sporophyte, specifically by the outer layer of cells known as the endothecium.

4. **Evaluating Option C**:
- **Statement**: "The spores germinate to produce primary protonema."
- **Analysis**: This statement is correct. When the spores germinate, they develop into a primary protonema, which is the first stage in the life cycle of mosses.

5. **Evaluating Option D**:
- **Statement**: "There are two neck canal cells in the archegonium."
- **Analysis**: This statement is incorrect. In Funaria, the archegonium typically contains a minimum of six neck canal cells and can have up to eleven. Therefore, stating there are only two neck canal cells is false.

### Conclusion:
- The incorrect statement about Funaria is **Option D**.
