What is the goal of cytology?

The goal of cytology is to understand cell structure and function. Cytology is the branch of biology that focuses on the study of cells, including their physiological properties, structure, organelles, interactions, and their roles in the overall function of living organisms. By examining the different types of cells and their specific characteristics, cytology provides insights into how cells contribute to the functioning of tissues and organs, ultimately aiding in the understanding of health and disease processes.

Although the other options mentioned involve important areas of biological study, they do not specifically focus on the cellular level, which is the primary concern of cytology. For example, examining body systems pertains more to physiology and anatomy, studying organism evolution is related to evolutionary biology, and analyzing tissue samples aligns with histology rather than the cellular focus central to cytology.
