What is cytology?

Cytology is the branch of science that focuses specifically on the study of individual cells. It examines cell structure, function, and the processes involving cells. Through cytological techniques, scientists and medical professionals can analyze cellular composition, detect abnormalities, and diagnose diseases, such as cancer, by assessing cellular morphology and changes. This field plays a crucial role in medical diagnostics and research.

The other options, while related to biological sciences and diagnostics, do not accurately define cytology. The study of tissues and organs refers to histology, the examination of blood samples is associated with hematology, and the study of genetic material pertains to genetics or molecular biology. Each of these fields focuses on different aspects of biological science, whereas cytology is distinctly centered on individual cells.
