Reproduction is synonymous with growth in

Options

A. Most of the fungi and Planaria
B. Desmids, diatoms and protozoans
C. Cyanobacteria, fungi and mosses
D. Mosses, algae and hydra

Answer

To solve the question "Reproduction is synonymous with growth in", we need to analyze the options provided and understand the concepts of growth and reproduction in different organisms. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding the Concepts**:
- **Reproduction**: This is the biological process by which new individual organisms are produced from their parents.
- **Growth**: This refers to the increase in size or mass of an organism. In unicellular organisms, growth often occurs through cell division.

2. **Identifying Unicellular Organisms**:
- In unicellular organisms, reproduction and growth can be synonymous because the process of cell division (reproduction) leads to an increase in the number of cells (growth).
- Examples of unicellular organisms include bacteria, amoeba, and certain protozoans.

3. **Analyzing the Options**:
- **Option 1: Fungi and Planaria**: Both are multicellular organisms. Not synonymous.
- **Option 2: Diatoms and Protozoans**: Both are unicellular organisms. This option is a strong candidate.
- **Option 3: Cyanobacteria, Fungi, and Mosses**: Fungi and mosses are multicellular. Not synonymous.
- **Option 4: Mosses, Algae, and Hydra**: Mosses are multicellular. Not synonymous.

4. **Conclusion**:
- The only option where reproduction is synonymous with growth is **Option 2: Diatoms and Protozoans**, as both are unicellular and their growth is directly linked to their reproductive processes.

### Final Answer:
Reproduction is synonymous with growth in **Diatoms and Protozoans**.
