Cytoplasm is crystallo-colloidal polyphasic solution, discovered bny Kolliker. It is actually

Options

A. Protoplasm
B. Protoplasm - Nucleus
C. Hyaloplasm - Organelle
D. Protoplasm - Organelle

Answer

**Step-by-Step Solution:**

1. **Understanding Cytoplasm**: Cytoplasm is described as a crystallocolloidal polyphasic solution. This means it has both crystalline and colloidal properties, and it consists of multiple phases.

2. **Historical Context**: The term "cytoplasm" was first introduced by Kolliker, which is an important historical fact related to its discovery.

3. **Components of Cytoplasm**: The cytoplasm contains various substances including:
- **Lipids**: Fats and oils that are essential for cellular structure and function.
- **Sugars**: Carbohydrates that provide energy.
- **Salts**: Electrolytes that help in maintaining osmotic balance and are crucial for cellular processes.
- **Acids and Bases**: These help in maintaining pH balance within the cell.
- **Proteins**: Essential for various cellular functions, including enzymes and structural components.

4. **Distinguishing Terms**:
- **Protoplast**: This term refers to the entire living part of the cell, including the cytoplasm and the nucleus.
- **Hyoplasm**: This is the fluid part of the cytoplasm, but it does not include the organelles or the nucleus.
- **Organelles**: These are specialized structures within the cytoplasm that perform specific functions.

5. **Analyzing Options**:
- **Protoplast**: Incorrect, as it refers to the entire living cell, not just the cytoplasm.
- **Protoplast and Nucleus**: This is the correct answer because it encompasses the cytoplasm and the nucleus, which is part of the protoplasm.
- **Hyoplasm**: Incorrect, as it only refers to the fluid part of the cytoplasm.
- **Protoplast and Organelles**: Incorrect, as it does not include the nucleus.

6. **Conclusion**: The most appropriate answer to the question is "Protoplast and Nucleus" because it accurately describes the cytoplasm as a crystallocolloidal polyphasic solution that includes both the cytoplasm and the nucleus.

**Final Answer**: Protoplast and Nucleus.
