Cell Biology
Cell biology is the study of cell structure and function, and it is based on the idea that the cell is the most basic unit of life. Concentrating on the cell allows for a more in-depth understanding of the tissues and organisms that cells comprise. Some creatures have only one cell, whilst others are structured into large cooperative groups with many cells. Cell biology, in general, is concerned with the structure and function of a cell, from the most generic qualities shared by all cells to the unique, extremely detailed tasks specific to specialised cells. Cell biology includes both prokaryotic and eukaryotic cells and comprises several subtopics such as cell metabolism, cell communication, cell cycle, biochemistry, and cell composition.
