The study related to the structure and function of cell is called as
(a) Physiology
(b) Cell biology
(c) Histology
(d) Cytology

Options

A. Physiology
B. Cell biology
C. Histology
D. Cytology

Answer

To solve the question regarding the study related to the structure and function of cells, we will analyze each option provided:

1. **Understanding the Question**: The question asks for the specific term that describes the study of the structure and function of cells.

2. **Evaluating Option (a) Physiology**: Physiology is the study of the functions and processes of living organisms and their parts. While it may include cellular functions, it is broader and not specifically focused on cells alone.

3. **Evaluating Option (b) Cell Biology**: Cell biology is the branch of biology that focuses on the study of cells, their physiological properties, their structure, the organelles they contain, and how they interact with their environment. This option directly relates to the structure and function of cells.

4. **Evaluating Option (c) Histology**: Histology is the study of the microscopic structure of tissues. While it involves cells, it is more about the organization of cells into tissues rather than the cells themselves.

5. **Evaluating Option (d) Cytology**: Cytology is the study of individual cells, their structure, function, and chemistry. While it is closely related to cell biology, it is often considered a subset of it.

6. **Conclusion**: Based on the evaluations, the most accurate answer to the question is **(b) Cell Biology**, as it encompasses the study of both the structure and function of cells comprehensively.

### Final Answer: (b) Cell Biology
