C. Endoplasmic matrix
D. Nucleoplasm

Answer

**Step-by-Step Solution:**

1. **Understanding Protoplast**: The protoplast is defined as the part of the cell that includes the cell membrane and the protoplasm. Protoplasm consists of the cytoplasm and the nucleus.

2. **Dividing Protoplast**: The protoplast can be divided into two main parts: ectoplasm and endoplasm.

3. **Characteristics of Ectoplasm**: The ectoplasm is the outer layer of the protoplast. It is in contact with the cell membrane, has a more liquid consistency, and is non-granulated.

4. **Characteristics of Endoplasm**: The endoplasm is the inner part of the protoplast. It is granulated, meaning it contains various organelles and particles.

5. **Cyclosis or Streaming**: The streaming movement, also known as cyclosis, occurs in the granulated endoplasm due to the presence of organelles and particles that can move around.

6. **Conclusion**: Therefore, the part of the protoplast that shows streaming or cyclosis is the endoplasm.

**Final Answer**: The endoplasm shows streaming or cyclosis.
