Non-flagellate' gametes occur in

Options

A. Ulothrix
B. Spirogyra
C. Funaria
D. Selaginella.

Answer

To solve the question "Non-flagellate' gametes occur in?", we will analyze the options provided and understand the characteristics of the gametes in each organism mentioned.

### Step-by-Step Solution:

1. **Understanding Gametes**:
- Gametes are reproductive cells that can be male (sperm) or female (egg).
- They can be classified into two types: motile (flagellate) and non-motile (non-flagellate).
- Motile gametes have flagella which aid in movement, while non-motile gametes do not have flagella and are unable to move.

2. **Analyzing the Options**:
- The options given are Eulothrix, Spirogyra, Funaria, and Saluginella.
- All these organisms are types of algae or related to algae.

3. **Identifying Non-Flagellate Gametes**:
- **Eulothrix**: This is a green algae that has motile gametes (flagellate).
- **Spirogyra**: This is also a green algae, but it is known for having non-flagellate gametes (non-motile).
- **Funaria**: This is a moss, and its gametes are also motile.
- **Saluginella**: This organism is similar to Eulothrix and has motile gametes.

4. **Conclusion**:
- Among the given options, Spirogyra is the only organism that has non-flagellate gametes. Therefore, the correct answer to the question is **Spirogyra**.

### Final Answer:
Non-flagellate gametes occur in **Spirogyra**.
