What Is Life Science?

What Is Life Science?

Life science, also known as '#biology', consists of all fields of science that involve the #scientific study of living organisms, like plants, animals, and human beings and their vital processes. Life is all around us; from gigantic whales that live in the oceans, to tiny germs that crawl around on your computer keyboard, Life Science explores the #origins, #evolution and expansion of life in all its forms.

But what exactly is life? What kinds of things are alive? At first, this question seems deceivingly simple. Don't we all know how to recognize what is living and what is not. For example, is a virus alive or dead? What are the characteristics of life? All forms of life grow and develop over time. This does not only mean that living things just get larger in size as times goes on, they also have the ability to rebuild and repair themselves when injured, or evolve due to their surroundings. Life forms can also reproduce, meaning new life can only come from other existing living creatures.

Because life sciences or biology covers such a broad area, it is typically separated into various branches or disciplines. In the most general sense, these disciplines are categorized based on the type of organism studied. For example: the study of plants called 'botany' is separated from that of animals known as 'zoology', or ecology which is the study of organisms and the environment. The study of the human body and its processes is regarded as the largest and most important discipline or field of life science.

Life science is one of the major branches or sections of scientific study. # Science can be real simple and is actually only about understanding the world you live in. However, no one scientist can study every aspect of this world we live in and the many different areas of science that exists can make it all a bit overwhelming if it is not grouped into related categories. #Categories, such as life science, allow scientists to focus on a set of similar topics and interact with others who are interested in the same questions and can make science much easier to understand.

Life science can be separated into various sub-branches such as: Botany, Zoology, Human anatomy, Ecology, Mycology and Entomology amongst others. Each sub-branch in turn may contain even more specific fields of study. Studying life sciences can be very rewarding and exciting. Biology teaches us to ask questions, make observations, evaluate evidence, and solve problems about all forms of life. Biologists learn how living things work, how they interact with one another, and how they evolve. They may study tiny cells under a microscope, insects in a rainforest, plants in a greenhouse, lions in the African grasslands or factors that affect the health of human beings!
