Classification

Definition

Classification is the systematic arrangement of living organisms into categories based on shared characteristics and relationships. This process allows researchers to organize biological diversity, making it easier to study and understand various aspects of life at the cellular level. In cell biology, classification helps in identifying different cell types, their functions, and their roles in larger biological systems, paving the way for advancements in research and technology.
