Botany
The scientific study of plants. Traditionally, botany also included the study of fungi and algae. However, these are now typically viewed as separate fields covered by mycologists and phycologists respectively.
Zoology
The scientific study of animals. Zoologists tend to specialize in a particular type of animal such as mammals or birds. This is also related to other fields such as wildlife biologists that tend to specialize in the animal population of a particular area or ecosystem.
Microbiology
The scientific study of microorganisms including bacteria, viruses, fungi and protozoa. In practice, these are also separate disciplines that include bacteriology, virology, mycology and protistology. Microbiology is also closely related to immunology that looks at how immune systems protect organisms from microorganisms.
Genetics
The scientific study of genes, heredity and variation in organisms. This is an advanced science that is still in the process of expanding as knowledge of genetics grows. For example, epigenetics that looks at changes in organisms caused by modification of gene expression rather than change to the DNA sequence itself.
Ecology
The science that looks at the relationships between organisms and their environment. This was historically one of the first branches of biology that is closely tied to evolutionary biology and natural history.
Evolutionary Biology
The study of the mechanisms that create the diversity of life on Planet Earth. These are known as evolutionary processes and include natural selection, common descent and speciation.
Cell Biology
The study of cells and their structure, behavior and function. Cells are viewed as the basic unit of life. Organisms aren't considered living in the traditional sense if they have no cells. For example, viruses have no cells and are viewed as existing at the boundary between living and non-living things.
Summary
Biology is an broad and deep field of study that includes many fields and sub-disciplines. The number of words that originate with biology number in the thousands. This reflects the incredible complexity of life and the scale of the practice of studying it.
