Statement (i): Histology is the study of histones
Statement (ii): Cytology is the study of tissues
Statement Analysis: Histology and Cytology Definitions
We need to evaluate the correctness of two statements regarding biological studies.
Statement (i): Histology is the study of histones
- Histology is the branch of biology concerned with the study of the microscopic anatomy of cells and tissues, specifically how the cells are arranged and structured within a tissue.
- Histones are a family of basic proteins that associate with DNA in the nucleus of eukaryotic cells, forming chromatin and enabling its compact structure.
- Therefore, histology is the study of tissues, not specifically histones. Statement (i) is incorrect.
Statement (ii): Cytology is the study of tissues
- Cytology is the branch of biology concerned with the study of cells, including their formation, structure, biochemical activities, and normal and abnormal functions.
- The study of tissues is known as histology.
- Therefore, cytology is the study of cells, not tissues. Statement (ii) is incorrect.
Conclusion
Since both statement (i) and statement (ii) are incorrect, the correct option is that both statements are incorrect.
