Circulatory movements of cytoplasm are seen in the

Options

A. Staminal hair cells of Rheo
B. Leaf cells of Hydrilla
C. Cells of onion pealing
D. Pith cells

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about where circulatory movements of cytoplasm, known as cyclosis, are observed.

2. **Defining Cyclosis**: Cyclosis refers to the movement of cytoplasm within a cell, which helps in the distribution of nutrients and organelles.

3. **Identifying Organisms with Cyclosis**: Cyclosis is generally observed in higher plants and animals, particularly in larger cells where the cytoplasm needs to circulate effectively.

4. **Analyzing the Options**:
- **Stamina**: This option is related to reproductive structures and does not specifically relate to cytoplasmic movement.
- **Hairs**: This option is too vague and does not refer to a specific cell type known for cyclosis.
- **Cells of the Rio**: This term is unclear and does not correspond to a known type of cell associated with cyclosis.
- **Leaf Cells of Hydrilla**: Hydrilla is an aquatic plant known for its leaf cells where cyclosis is prominently observed.
- **Cells of Onion Peeling**: Onion cells are typically used for observing cell structure but do not exhibit significant cyclosis.
- **Peat Cells**: These cells are involved in sap transport but are not primarily known for cyclosis.

5. **Conclusion**: Based on the analysis, the correct answer is **leaf cells of Hydrilla**, as they are known to exhibit circulatory movements of cytoplasm.

### Final Answer:
The circulatory movements of cytoplasm are seen in the **leaf cells of Hydrilla**.
