Life Science

Life science refers to the study of life, what we call in technical terminology is Biology. It studies the life in all its aspects that is its beginning, development and all related fields like micro biology, genetics, bio chemistry, bio informatics, bio physics, bio technology etc. The study of basic elements of the life science is started from the school level itself.


Branches of Life Science

Life science or biology is divided into following basic branches:


Botany is the science or study of plant life. It is one of the two main branches of biology. There are over 350,000 different species of plants in the world. Scientists called botanists study all aspects of plant life, including where plants live and how plants grow.


Zoology is the study of animals. Zoologists try to answer many problems about animals. For example, researches were conducted on activities of animal lives. They also examine how different species are related to one another and how species have evolved (changed over long periods). Zoologists observe the ways animals interrelate with one another and their surroundings. Effect of animals and people on each other was tried to found out by zoologists.

Molecular Biology

Molecular biology is the learning of those molecules that regulate the molecular course in cells. For example, genetic information is stored in huge molecules in the cells of organisms. The way in which these molecules alter their information into chemical reactions gives a living being its particular individuality and characteristics and is necessary for its existence. Molecular biology is a relatively new area of biology and has provided a greater understanding of what life is and how life works.


Anatomy studies the structure of living things. Anatomists investigate how parts are related in organisms. Histology studies tissues, and cytology with the tiny structures of individual cells. Relative anatomy studies similarities and differences in the body structure of animals and provides evidence to how certain animals might have changed over the period of time.

Other advance branches of the subject include bio informatics, genetics, etc.

Life Science Textbooks

The content of the textbooks of life science varies according to the target readers. For the beginners of the subject, like for the grade seven student a basic introduction of the subject is there as a content of the book like the basic features and essential characteristics of living things, classification of plants and animals etc. As the level of education rises, the content of the textbooks also rises to the finer elements of the subject like respiration in living beings, cell division, reproduction in living beings and function of various parts of cells.

For the students who take life science as the subject of further study, their textbooks are based on the deeper aspects of subject and associated fields like zoology, botany, modern branches of subject like bio chemistry, bio technology, genetics etc. Various life science journals are also published by the researching bodies across the globe for updating the researchers about the latest development of the subject.

Life Science Projects

Life science projects also depend upon the number of factors like that of science experiments. Basic projects comprise of the models of various parts and processes of the subject and are used for illustrative purposes.

On the other hand, various projects like bio diesel and other bio fuels which are environment friendly, Recombinant DNA technology, projects on medicinal plants etc are undertaken by the government of the nation for the purpose of scientific progress and development.

Life Science Industries

The scope of industries related with the subject of life science ranges from pharmaceutical sector to raw and processed food industry to leather sector etc. Constant research and innovation in the field of life science is the fuel of the industry and they are benefited by the new researches in the subject to a great extent. After the globalization of many countries, this industry is soaring new heights as the benefits of various researches and findings are exchanged by many countries mutually. Due to the ever growing tendency of this industry, there is a great and prospective career apart from the traditional career of doctor and health care executive. There is a great demand of life science experts in pharmaceutical sector at all the levels, in food industry for quality and standard functions etc. Now days, there is also a great and lucrative career in the industries which manufacture healthcare equipments.
