In spriogyra lateral conjugation takes place in the cells of

Options

A. two adjacent cells of same filament
B. two cells of different filaments
C. among three filaments
D. within one cell of a filament

Answer

**Step-by-Step Solution:**

1. **Understanding Lateral Conjugation**: Lateral conjugation is a type of sexual reproduction that occurs in certain algae, including Spirogyra. It involves the fusion of two adjacent cells.

2. **Identifying the Cells Involved**: In Spirogyra, lateral conjugation specifically occurs between two adjacent cells. This means that the cells must be next to each other in the same filament.

3. **Eliminating Other Options**:
- The option "two cells of different filaments" is incorrect because lateral conjugation occurs within the same filament.
- The option "among three filaments" is also incorrect as lateral conjugation does not involve multiple filaments.
- The option "within one cell of a filament" is incorrect because lateral conjugation involves two separate cells.

4. **Conclusion**: Therefore, the correct answer is that lateral conjugation takes place in the cells of two adjacent cells of the same filament in Spirogyra.

**Final Answer**: Lateral conjugation in Spirogyra takes place in the cells of two adjacent cells of the same filament.
