Plasmasol or sol part of cytosol in contact is known as

Options

A. Hyalosome
B. Hyaloplasm
C. Endoplasm
D. Both B and C

Answer

To answer the question "Plasmasol or sol part of cytosol in contact is known as," we need to break down the components of cytosol and identify the specific part referred to as plasmasol.

### Step-by-Step Solution:

1. **Understanding Cytosol**: Cytosol is the fluid component of the cytoplasm, which is the area between the cell membrane and the nucleus. It is primarily composed of water, salts, and organic molecules.

2. **Components of Cytosol**: Cytosol consists of two main parts:
- **Endoplasm (Hyloplasm)**: This is the inner part of the cytosol. It is more granular and denser compared to the ectoplasm. It contains various organelles and is involved in many cellular processes.
- **Ectoplasm**: This is the outer part of the cytosol. It is in direct contact with the plasma membrane (also known as the plasmalemma). The ectoplasm is non-granulated and more gel-like.

3. **Identifying Plasmasol**: The term "plasmasol" refers specifically to the sol part of the cytosol that is in contact with the cell membrane. This corresponds to the ectoplasm, as it is the part that interfaces directly with the plasma membrane.

4. **Conclusion**: Therefore, the plasmasol or sol part of the cytosol in contact with the plasma membrane is known as the **ectoplasm**.

### Final Answer:
The plasmasol or sol part of cytosol in contact is known as **ectoplasm**.
