Understanding Biology

04 Jun Understanding Biology

Science tuition covers a wide range of natural studies. Biology is one of the core subjects covered in science education by most syllabi. Biology is a natural science that studies life and living organisms. This includes their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.

Despite the complexity of biological sciences, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life. Genes are recognized as the basic unit of heredity. Evolution is recognized as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis.

From ecology to molecular biology, the science of biology studies them all. Biology is the science of life. Its name is derived from the Greek words “bios” (life) and “logos” (study). Biologists study the structure, function, growth, origin, evolution, and distribution of living organisms. Biology as a subject is essential in recognizing the species that coexist with mankind. Science tuition focuses on the understanding of the survival processes of species.

Many aspects of biological systems seem insignificant. The broader picture that contains ecological concepts and ecosystems, however, is only complete with all living organisms. Biological studies can be subdivided into theoretical biology and experimental biology. Theoretical biology uses mathematical methods to formulate quantitative models. Experimental biology on the other performs empirical experiments to test the validity of proposed theories. It aims to understand the mechanisms underlying life. The main focus is on how it appeared and evolved from non-living matter about 4 billion years ago through a gradual increase in the complexity of the system.

Modern biology is a relatively recent development. Sciences related to and included within it have been studied since ancient times. Natural philosophy was studied as early as the ancient civilizations of Mesopotamia, Egypt, the Indian subcontinent, and China. The origins of modern biology and its approach to the study of nature are most often traced back to ancient Greece. While the formal study of medicine dates back to Hippocrates, it was Aristotle who contributed most extensively to the development of biology.
