Introduction to Cell Biology is a fundamental area of biological science that focuses on the study of cells, their physiological properties, structures, organelles, interactions, and functions. It serves as the basis for understanding the building blocks of life, examining how cells contribute to the overall functioning of organisms. This discipline covers topics such as cell theory, cell metabolism, cell signaling, and the cell cycle, emphasizing the importance of cell biology in fields like genetics, microbiology, and biotechnology. Through the exploration of both prokaryotic and eukaryotic cells, students gain insights into the complexity and diversity of life at the cellular level.
