Options

A. Multicellular organisms
B. Unicellular organisms
C. Both unicellular & multicellular organisms
D. None

Answer

To answer the question "Reproduction is synonymous with growth in," we need to analyze the relationship between reproduction and growth in different types of organisms.

### Step-by-Step Solution:

1. **Define Reproduction**:
- Reproduction is the biological process by which new individual organisms are produced from their parents. This can occur through various methods, including sexual and asexual reproduction.

2. **Define Growth**:
- Growth refers to the increase in size or number of cells in an organism. It can be characterized by an increase in the overall mass or volume of the organism.

3. **Examine Unicellular Organisms**:
- In unicellular organisms, such as amoeba, reproduction occurs through a process called binary fission. Here, one cell divides to form two daughter cells.
- During this process, the number of cells increases, which also signifies growth. Thus, in unicellular organisms, reproduction and growth occur simultaneously; as one organism reproduces, it also increases in cell number.

4. **Examine Multicellular Organisms**:
- In multicellular organisms, such as humans, reproduction involves producing offspring (e.g., babies). However, this process does not directly correlate with the growth of the parent organism.
- Growth in multicellular organisms is characterized by an increase in size, height, or mass, which occurs independently of the reproduction process.

5. **Conclusion**:
- Therefore, reproduction is synonymous with growth only in unicellular organisms, where both processes are interconnected. In contrast, in multicellular organisms, reproduction and growth are distinct processes.

### Final Answer:
Reproduction is synonymous with growth in **unicellular organisms**.
