Circulation type of protoplasmic streaming is studied in

Options

A. Staminal hair cell of Tradescantia
B. Hydrilla leaf cells
C. Vallisneria leaf cells
D. Both B and C

Answer

**Step-by-Step Solution:**

1. **Understanding Protoplasmic Streaming:**
- Protoplasmic streaming refers to the movement of the cytoplasm within a cell. This movement is essential for transporting nutrients, organelles, and other substances throughout the cell.

2. **Mechanism of Protoplasmic Streaming:**
- The movement of cytoplasm is facilitated by microfilaments, which are part of the cytoskeleton. These microfilaments are primarily composed of actin filaments, which play a crucial role in cellular movement and structure.

3. **Importance of Protoplasmic Streaming:**
- Protoplasmic streaming is particularly important in large cells where diffusion alone would be insufficient for the distribution of materials. It allows for efficient transport and communication within the cell.

4. **Organism Used for Study:**
- The circulation type of protoplasmic streaming is commonly studied in the staminal hair cells of the plant *Tradescantia*. These cells are ideal for observation because they are easily accessible and lack pockets, making them suitable for microscopic examination.

5. **Observation Under Microscope:**
- The staminal hair cells of *Tradescantia* can be observed under a microscope to study the protoplasmic streaming. The superficial location of these cells allows for clear visibility of the streaming process.

**Final Answer:**
The circulation type of protoplasmic streaming is studied in the staminal hair cells of *Tradescantia*.
