Cell biology is the study of cell structure and performance, and it revolves around the conception that the cell is the basic unit of life. Cell biology explains the structure, organization of the organelles they contain, their physiological properties, metabolic processes, signaling pathways, life cycle, and interactions with their environment. This is done each on a microscopic and molecular level because it encompasses prokaryotic cells and eukaryotic cells. Knowing the elements of cells and the way cells work is prime to any or all biological sciences. On the total, cell biology focuses on the structure and performance of a cell, from the foremost general properties shared by all cells, to the distinctive, highly intricate functions particular to specialized cells. Research in cell biology is closely associated with genetic science, organic chemistry, biological science, immunology, and organic process biology.
