Posted on

Branches of biology, including ecology, genetics, taxonomy, zoology, mammology, herpetology, ichitology, carcinogenesis, and others will be discussed in this article.

Biology is the study of living things. As we know, the study of living things is very broad because living things consist of various types and different characteristics. Of course, this makes the study of biological sciences have a very broad scope.

Therefore, biology is divided into several branches to be more specific and detailed when studying a type of living thing. Well, this time we will discuss about several branches of biology to add to your insight.

Biology Science Branches

Biology is a branch of science that studies living organisms and their lives, which includes the sciences of evolution, genetics, plants, animals, identification, to taxonomy.

There are many branches of science studied in the field of biology. These biology branches  are divided based on the object of study. The following is a list of scientific branches studied in the scope of biology.

The study of the application of quantum mechanics and theoretical chemistry to biological objects and problems

17. Botany

Botany is the study of organisms in the kingdom Plantae, otherwise known as plants. The word botany comes from the adjective botanic, which in turn comes from the ancient Greek word botane, referring to plants, grasses, and meadows. Botany also has another, more specific meaning; it can refer to the biology of a particular plant species (e.g. botany of flowering plants) or to plant life in a specific area (e.g. rainforest botany).

red colored plant

People who study botany are also known as botanists. Botany along with plant studies also includes the study of fungi and algae; hence these three major groups of organisms are included under the International Botanical Congress.

Branch of botany: Botany is the scientific study of plants, or multicellular organisms, that carry out photosynthesis. As a branch of biology, botany is sometimes referred to as plant science or plant biology.

18. Briology

Briology (from the Greek bryon) is a branch of botany concerned with the scientific study of mosses, liverworts, and hornworts. Briologists are people who have an interest in observing, recording, classifying or researching bryophytes.

This field is often studied together with lichenology because of its similar morphology and ecology, although in fact bryophytes and lichens are not classified in the same kingdom.

19. Dendrology

Dendrology is a branch of biology that studies trees and other woody plants, such as lianas and shrubs. This branch of science is mainly studied in the field of botany and its application, forestry. In this science, morphology and anatomy are mainly studied to obtain the basics of tree recognition.

The term ecology is often considered a foreign term that is rarely heard by the public. In fact, most people think of ecology as the same as ecosystems, when in fact they are different.

Ecology was introduced by a biologist from Germany named Ernst Heinrich Philipp August Haeckel or commonly known as Ernst Haeckel.

Ecology comes from the Greek words oikos and logos. Oikos means habitat, while logos means knowledge.

So if explored further, ecology has a meaning as a science that studies the relationship between fellow organisms and the relationship between organisms and their environment. The meaning also varies, because some experts have different meanings.

21. Embryology

Embryology

Embryology or embryo science is the field of science that studies how single cells divide and change during development to form multicellular organisms. This process is called embryogenesis. Embryology can be divided into several types:

In short it can also be said that genetics is the science of genes and all its aspects. The term “genetics” was introduced by William Bateson in a personal letter to Adam Chadwick and he used it at the 3rd International Conference on Genetics in 1906.

The field of genetic studies starts from the subcellular (molecular) area to the population. In more detail, genetics seeks to explain:

  • information-carrying material to be inherited (genetic material),
  • how the information is expressed (genetic expression), and
  • how the information is transferred from one individual to another (genetic inheritance).
