Biology is the study of all the concepts of natural science of life and living organisms. It comprises of living organisms’ physical structure, important molecular interactions, chemical processes, physiological mechanism, development and evolution. Biology also tells us how cells and organisms work. Studying Biology as a science helps to leverage human life in a lot of ways.
Biology is subdivided into separate branches for convenience of study, though all the subdivisions are interrelated by basic principles. Thus, while it is custom to separate the study of plants (botany) from that of animals (zoology), and the study of the structure of organisms (morphology) from that of function (physiology), all living things share in common certain biological phenomena—for example, various means of reproduction, cell division, and the transmission of genetic material.
