Real growth is

Options

A. protoplasmic growth
B. Cell wall growth
C. Growth in size
D. Growth in volume

Answer

### Step-by-Step Solution:

1. **Understanding Growth**:
- Growth in biological terms refers to an increase in size and mass of an organism or its parts. It can be measured in terms of height, weight, volume, etc.

2. **Defining Real Growth**:
- Real growth is characterized as an irreversible change. This means that once growth occurs, it cannot be undone. It represents a permanent increase in size.

3. **Types of Growth**:
- There are different types of growth in plants, including:
- **Protoplasmic Growth**: This refers to the growth of the living part of the cell, which includes the cytoplasm and nucleus.
- **Cell Wall Growth**: This refers to the expansion of the cell wall, which can occur without a corresponding increase in protoplasm.
- **Growth in Size**: This is a general term that can apply to any increase in dimensions.
- **Growth in Volume**: This specifically refers to the increase in the three-dimensional space occupied by an organism or its parts.

4. **Identifying Real Growth**:
- Among the options provided, "protoplasmic growth" is the most accurate representation of real growth. This is because it involves the living components of the cell and signifies a permanent increase in size.

5. **Conclusion**:
- Therefore, the correct answer to the question "Real growth is" is **protoplasmic growth**.

### Final Answer:
Real growth is **protoplasmic growth**.
