What is biology? What is the meaning of studying things?

(1) Biological definition: Biology is a science that studies the structure, function, occurrence and development of organisms (including plants, animals and microorganisms). Part of natural science. The purpose is to clarify and control life activities, transform nature and serve the practice of agriculture, industry and medicine.

For thousands of years, China has accumulated rich knowledge about plants, animals, microorganisms and human bodies in the practice of agriculture, forestry, animal husbandry, fishing and medicine. From 65438 to 0859, the British naturalist Darwin published The Origin of Species, which established the materialist view of biological evolution and promoted the rapid development of biology.

(2) Significance of learning biology: Biology is closely related to many aspects of human life. Biology, as a basic science, is traditionally the basis of agronomy and medicine, involving agriculture, animal husbandry, fisheries, medical care, pharmacy, health and so on. With the continuous development of biological theory and method, its application field is also expanding.

The influence of biology has broken through the above-mentioned traditional fields and extended to food, chemical industry, environmental protection, energy and metallurgical industries and so on. If bionics is considered, it will also affect electronic technology and information technology. Population, food, environment and energy are global issues that attract worldwide attention.

Extended data:

Historical origin of biology: In ancient times when natural science was underdeveloped, people were puzzled by colorful biology. They often regard life and inanimate objects as two completely different and unrelated fields, and think that life is not dominated by the laws of motion of inanimate objects.

Many people also attribute all kinds of life phenomena to an immaterial force, that is, the role of "vitality". These groundless speculations have been gradually abandoned with the development of biology and have no place in modern biology.

Since the 20th century, especially since the 1940s, biology has absorbed the achievements of mathematics, physics and chemistry, and gradually developed into an accurate, quantitative and molecular science. People have realized that life is a form of material movement.

The basic unit of life is the cell, which is a material system composed of protein, nucleic acid, lipid and other biological macromolecules. Life phenomenon is the expression of the comprehensive movement and transmission of matter, energy and information in this complex system. Life has many characteristics that inanimate matter does not have.
