Biology or life science is the study of life, and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.[1] Modern biology deals with a very broad, eclectic, and consists of various branches and sub-disciplines. In general, all branches of biology are united by the basic concepts that govern all biological research, namely the concepts of cells, genes, and evolution. Cells are recognized as the basic unit of life, genes are recognized as the basic unit of inheritance, and evolution is assumed to be the mechanism that drives the creation of new species. In addition, the survival of living things is believed to occur due to consumption behavior, changes in energy and regulations that maintain the stability and vitality of conditions in the body.[2]

The subdiscipline of biology is defined based on the scale of the organism being studied, the type of organism being studied, and the methods used to study it, including:[3]

Biochemistry studies the chemistry of life.
Molecular biology is concerned with the interactions between biological molecules.
Botany studies plant biology
Cellular biology examines the basic unit of all life, namely the cell.
Physiology studies the physical, and chemical functions of organ tissues, and organ systems of an organism.
Evolutionary biology examines the processes that produce biodiversity; and ecology studies the interactions between organisms and their environment.
A person who is an expert in the field of biology is called a biologist, biologist, or biologist.

The term biology comes from the Greek word , bios, which means "life", and the suffix -λογία, -logia, which means "science."[4][5] The Latin form of the word (biology) was first used by Linnaeus (Carl von Linné) in his work entitled Bibliotheca botanica in 1736. The word was used again in 1766 by Michael Christoph Hanov in his writings entitled Philosophiae naturalis sive physicae: tomus III, continens geological, biologist, phytologian generalis. His German translation, Biologie, first appeared in a translation by Linnaeus in 1771. In 1797, Theodor Georg August Roose used the term in his predecessor to his book Grundzüge der Lehre van der Lebenskraft. Karl Friedrich Burdach in 1800 used this term in a narrower sense, namely human research from a morphological, physiological, and psychological point of view (Propädeutik zum Studien der gesammten Heilkunst). The term biology in its modern sense only appeared in the book Biologie, oder Philosophie der lebenden Natur (1802–22) written by Gottfried Reinhold Treviranus. It is written in the book.
