_____ is known as cytoplasm minus all inclusions and organelles.

Options

A. Hyaloplasm
B. Stroma
C. Protoplasm
D. Protoplast

Answer

To solve the question "_____ is known as cytoplasm minus all inclusions and organelles," we need to identify the term that describes the remaining fluid part of the cytoplasm after excluding all organelles and inclusions.

### Step-by-Step Solution:

1. **Understanding Cytoplasm**:
- Cytoplasm is the jelly-like substance within a cell that contains all the organelles and inclusions. It is the area between the cell membrane and the nucleus.

2. **Identifying Inclusions and Organelles**:
- Inclusions refer to non-living components such as stored nutrients or pigments.
- Organelles are the living components of the cell, such as mitochondria, endoplasmic reticulum, and the nucleus.

3. **Defining the Term**:
- The question asks for the term that represents the cytoplasm without any organelles or inclusions.

4. **Considering the Options**:
- **Hyloplasm**: This term refers to the clear fluid portion of the cytoplasm, excluding all organelles and inclusions.
- **Stroma**: This term is specific to the fluid found in chloroplasts and does not apply to the general cytoplasm.
- **Protoplasm**: This includes both the cytoplasm and the nucleus, thus it contains organelles.
- **Protoplast**: This term refers to the living part of the cell, including the cytoplasm and nucleus, hence it also contains organelles.

5. **Conclusion**:
- The correct answer is **Hyloplasm**, as it is defined as the cytoplasm minus all inclusions and organelles.

### Final Answer:
**Hyloplasm**
