Genophore term was coined by Hans Ris for

Options

A. Genetic material of virus
B. Genetic material of fungus
C. Bacterial chromosome
D. Stalk supporting spores.

Answer

### Step-by-Step Solution:

1. **Understanding the Term "Genophore":**
- The term "genophore" refers to the genetic material found in certain organisms.

2. **Origin of the Term:**
- The term was coined by Hans Ris, a notable scientist in the field of microbiology.

3. **Context of Prokaryotes:**
- Genophores are specifically associated with prokaryotic organisms, which include bacteria. Prokaryotes are unicellular organisms that lack membrane-bound organelles and do not have a true nucleus.

4. **Structure of Genophore:**
- In bacteria, the genetic material is organized in a structure called the nucleoid, which is not surrounded by a nuclear membrane. The genophore is typically described as a single circular double-stranded DNA molecule.

5. **Differentiation from Eukaryotic Chromosomes:**
- The term "genophore" was introduced to differentiate the bacterial chromosome from eukaryotic chromosomes, which are linear and found within a defined nucleus.

6. **Conclusion:**
- Based on this understanding, the correct answer to the question is that the term "genophore" was coined by Hans Ris for the bacterial chromosome.

### Final Answer:
The term "genophore" was coined by Hans Ris for the bacterial chromosome.
