![]() ![]() Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. īiologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations. Finally, all organisms are able to regulate their own internal environments. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Another major theme is evolution, which explains the unity and diversity of life. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. Put those two words together and you get the "study of life.Biology is the scientific study of life. The word biology comes from the Greek words "bios" which means life and "logia" which means "study of". Plants gather energy from the Sun through photosynthesis. For example, humans use food such as vegetables and meat. ![]() Energy - All living organisms are able to use external substances for energy.For example, humans are able to regulate their body temperature to 98.6 degrees. Homeostasis - Homeostasis is the process by which an organism or cell is able to regulate its conditions.Genetics - Genetics is the study of how organisms pass on features and traits from generation to generation.Every living organism is made up of one or more cells. The cell - The cell is the fundamental unit of all life. ![]() There are many branches of science that are part of biology including ecology (how organisms interact with their environment), agriculture (the study of producing crops from the land), biochemistry (the chemical reactions needed to support life), botany (the study of plants), physiology (how living organisms function), and zoology (the study of animals).īiology is based on some key theories and fundamentals: This includes such subjects as the cell, genes, inheritance, microorganisms, plants, animals, and the human body. Biology is the branch of science that studies life and living organisms. ![]()
