Agriculture , Science , Chemistry , Paleontology , Physics The science and study of life and of plant, animal, and other types of organisms. The science of life and living organisms, biology studies the form, structure, function, growth and development, behavior and interaction of all living things. Because there is such a huge variety of living things on the earth , the science of biology has many different branches and areas of study.
Biologists also use other sciences to research life.
Without chemistry and physics , much of the knowledge we have gathered about life would have been impossible to collect. In an effort to answer the what is life question, much of the history of biological study has been focused on trying to classify and define life forms. The four categories above led to the development of many subcategories as biologists learn more about the depth and complexity of living things. Anatomy, physiology, embryology, evolution and paleontology are just of few of its subcategories. Embryology Study of the formation and development of organisms from the zygote, or fertilised egg.
