Life Sciences

Biology students are highly encouraged to go through this article highlighting the main concepts of life sciences and why we should study it. Read this Biology article, created after thorough research by subject experts, to understand and learn about Life Science, important terms related to it, the different branches under Life Sciences and some relevant questions related to the topic.

What is Life Science?

Life science is the study of living organisms and different life processes. It helps in understanding biological concepts at molecular and cellular levels. Life science is a vast study field that covers everything- from the ocean’s surface to the microorganisms in your gut. It is also called Biological Science, as it involves the study of how living beings dwell and how we may improve our lives. Life science is an umbrella term that includes the different branches related to Life Science, which we will cover in this article.

What is the Importance of Life Sciences?

The study of life sciences empowers us to answer fundamental questions such as-

• Where did we come from? 

• What are we made of? 

• Is our existence a miracle, or is there some science behind it? 

• How are we interlinked with the natural world?

Life sciences touch every area of our existence - from health care to the environment to advancements in medicine. They provide an understanding of life, the cycle of existence, and degeneration and illness. Life sciences help us comprehend how life is interconnected with our world, which further aids researchers to integrate the latest advancements in academic subjects with new, improved analytical tools from other fields of science. The study of the Life Sciences also allows the development of innovative medical devices, thereby directly improving human health.

Basic Branches Under Life Sciences

Here are some basic branches of life science examples and their definitions.

1. Anatomy: The study of structure, functions, and parts of the human body.

2. Biochemistry: The study of the chemical reactions required for life to exist and function, usually on the cellular level.

3. Biotechnology Life Sciences: The study of the manipulation of living matter, including genetic modification and synthetic biology.

4. Botany: The study of plants.

5. Cell biology: The study of the cell and the molecular and chemical interactions occurring within a living cell.

6. Ecology: The study of the interactions of living organisms and the non-living elements of their environment.

7. Entomology: The study of insects.

8. Evolutionary Biology: The study of the origin and descent of species over time

9. Genetics: The study of genes and heredity.

10. Microbiology: The study of microorganisms and their interactions with other organisms.

11. Molecular Biology: The study of biology and biological functions at the molecular level.

12. Neuroscience: The study of the nervous system.

13. Physiology: The study of the functioning of living organisms and the organs and parts of living organisms.

14. Toxicology: The study of the effects of chemicals on living organisms.

15. Zoology: The study of animals, including classification, physiology, development, and behaviour.

Lesser Known Facts About Life Sciences

1. The human body has around 38 trillion cells, which carry out different functions essential for everyday living.

2. Bacteria are a crucial part of the ecosystem and aid processes such as the production of gases like oxygen, carbon dioxide and nitrogen and minerals like nitrogen, sulphur, etc.

3. The human brain contains 100 billion neurons, forming more connections than there are stars in the Milky Way galaxy.

4. The DNA of humans is 99.9% identical to that of other humans.

5. The diversity of life on Earth results from billions of years of evolution through natural selection.
