Movement of Spirogyra gametes is

Options

A. ciliary
B. cyclosis
C. amoeboid
D. chemotatic

Answer

**Step-by-Step Solution:**

1. **Understanding Spirogyra**: Spirogyra is a filamentous green alga that reproduces sexually by forming gametes. It is important to know the characteristics of these gametes to understand their movement.

2. **Analyzing the Movement Options**:
- **Ciliary Movement**: This type of movement is associated with the presence of cilia, which are hair-like structures that beat to create movement. This is not applicable to Spirogyra gametes as they do not possess cilia.
- **Cyclosis**: This refers to the movement of the cytoplasm within a cell, which is not related to the movement of gametes. Therefore, this option is also incorrect.
- **Amoeboid Movement**: This type of movement is characterized by the formation of pseudopodia, which are extensions of the cell that allow for movement. Spirogyra produces non-flagellate gametes that exhibit amoeboid movement.
- **Chemotactic Movement**: This movement is directed by chemical signals. Since Spirogyra gametes do not move in response to chemicals, this option is incorrect.

3. **Conclusion**: After evaluating all the options, the correct answer is that the movement of Spirogyra gametes is amoeboid.

**Final Answer**: The movement of Spirogyra gametes is amoeboid.
