Biology specifies the cell as life’s basic unit, genes as heredity’s basic unit, and evolution as the generator that drives the species’ creation and extinction.
Biological science may seem very complex but some specific unifying concepts combine it into a single, consistent field. Biology studies these living organisms’ chemical processes, physical structure, physiological mechanisms, molecular interactions, evolution, and development. An organism means an alive entity having one cell such as bacteria, or several cells such as plants, fungi, and animals. So, biology is the science which studies life and alive organisms. The Greek words bios and logos are the origins of the term “biology”.
