Cytoplasm is composed of all cell organelles except nucleus. The contents of nucleus are separated from cytoplasm by the nuclear membrane. Nucleus and muclear membrane together form nucleoplasm. Cytoplasm and nucleoplasm are together referred to as

Options

A. protoplast
B. cytonucleus
C. protoplasm
D. nucleolus

Answer

To answer the question, "Cytoplasm and nucleoplasm are together referred to as," we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Components**:
- Cytoplasm includes all cell organelles except the nucleus.
- The nucleus is separated from the cytoplasm by the nuclear membrane.

2. **Identify the Nucleus and Nuclear Membrane**:
- The nucleus contains genetic material and is surrounded by the nuclear membrane.
- The space within the nucleus is known as nucleoplasm.

3. **Combine the Terms**:
- Cytoplasm (the jelly-like substance outside the nucleus) and nucleoplasm (the substance within the nucleus) are both essential components of a cell.

4. **Define the Combined Term**:
- The term that refers to both cytoplasm and nucleoplasm together is "protoplasm."

5. **Evaluate the Options**:
- The options provided include terms like protoplast, cytonucleus, protoplasm, and nucleolus.
- Among these, "protoplasm" is the correct term that encompasses both cytoplasm and nucleoplasm.

### Final Answer:
Cytoplasm and nucleoplasm together are referred to as **protoplasm**.
