What are the different branches of biology?

Answer 1

"Branches of Biology
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. Depending on their discipline, biologists usually research one or more of the following categories:

Microbiology, a study dealing with the structure and existence of microorganisms, which are tiny life forms such as a bacteria or a virus;
Zoology, which is the study of animal life;
Botany, which is focused on plant life;
And physical anthropology, where scientists study human life, such as our existence and how we interact with other life forms.
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. Some of the other subdivisions of biology are:-

Physiology
Study of the vital functions and basic activities of living organisms - cells, tissues, organs, and organ systems - and their parts, in relation to the whole.
Embryology
Study of the formation and development of organisms from the zygote, or fertilised egg. Confined mainly to multi-celled organisms.
Taxonomy
Hierarchical classification of natural organisms indicative of their structures and differences.
Genetics
Study of inheritance and variation in organisms, and mechanisms by which these operate; causes of similarities and differences among related individuals.
Ecology
Study of relationships between organisms and their environment; the interactions of individuals within groups and with their suroundings.
Morphology
The study of the shapes of plants and animals.
Molecular Biology
Study of chemical processes at the level of large organic molecules such as proteins and nucleic acids.
Biochemistry
Study of the chemical processes within living systems as a whole.
Microbiology
The study of micro-organisms - their structure, function, and significance."
