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

### Step-by-Step Solution:

1. **Understanding the Concepts**:
- Reproduction and growth are two fundamental biological processes. Growth refers to an increase in size or mass, while reproduction is the process by which organisms produce new individuals.

2. **Identifying Organisms**:
- Certain organisms exhibit a close relationship between growth and reproduction. For example, in some unicellular organisms, growth can directly lead to reproduction.

3. **Prokaryotic Cells**:
- In prokaryotic cells (like bacteria), growth often results in binary fission, where one cell divides into two. Here, growth and reproduction are closely linked.

4. **Eukaryotic Cells**:
- In eukaryotic organisms (like fungi), growth can occur through various methods, but reproduction can also happen independently of growth. Therefore, the relationship is not as direct as in prokaryotes.

5. **Examples of Organisms**:
- The question mentions different groups of organisms. For instance, cyanobacteria (prokaryotic), fungi (eukaryotic), and moss (a bryophyte) have different modes of reproduction and growth.

6. **Analyzing Options**:
- The question provides options regarding which organisms have reproduction synonymous with growth. After analyzing the options, it becomes clear that certain eukaryotic organisms (like protozoans) exhibit a closer relationship between growth and reproduction compared to others.

7. **Conclusion**:
- The correct answer is option two, which includes organisms where reproduction is synonymous with growth.
