What is Biology and Life Science?: Introduction

To understand biology and life science difference, it is important to know what they are. Life science and biology are closely related fields but have some distinct differences. Here's a description of the characteristics of biology and life science.

Biology: Biology is an extensive scientific field that aims at investigating living organisms, encompassing their anatomy, function, physiology, development, origin, evolutionary changes, and geographic dispersion. It comprises a plethora of sub-disciplines such as botany, zoology, microbiology, genetics, ecology, and more. Biology sets out to unravel the fundamental principles and mechanisms that govern life at different levels, such as molecular, cellular and organismal levels and ecosystems. It explores both the diversity and unity of life on Earth.

Life Science: Life science, also known as the biological sciences, refers to the scientific study of living organisms and their processes. It is a broader term that encompasses biology and other related disciplines. Life science incorporates various fields that contribute to the understanding of life, including biology, biochemistry, biotechnology, genetics, ecology, physiology, and others. It undertakes a multidisciplinary approach to exploring life at different levels and addresses biological questions.

Differences Between Biology and Life Science




Life Science 


Biology is a specific branch of science that focuses on the study of living organisms, including their structure, function, growth, origin, evolution, and distribution. 

Life sciences is a broader term that focuses on various disciplines including biology, biochemistry, genetics, ecology, physiology, and more.

Interdisciplinary approach

Biology is more specific to studying living organisms.

Life science often takes an interdisciplinary approach and integrates the knowledge of physics, chemistry, biology and computer science to understand complex biological phenomena. 

Research areas 

Biology covers a wide range of research areas within the study of living organisms, including molecular biology, cellular biology, genetics, physiology, ecology, and evolution. 

Life sciences, in addition to these areas, can also include other disciplines such as biochemistry, biophysics, neuroscience, microbiology, immunology and biomedical sciences.


Biology often focuses on fundamental research and understanding the underlying principles of life. 

Life sciences encompasses both fundamental and translational research areas and can be applied in healthcare, pharmaceuticals, biotechnology, agriculture, and environmental sciences.

Levels of study

Biology generally examines living organisms at multiple levels, from molecules and cells to whole organisms and considers both microscopic and macroscopic perspectives. 

Life sciences, while also considering these levels of study, may extend beyond individual organisms to include population dynamics, ecosystems, and global-scale interactions.


To summarize, this article sheds light on the differences between the two branches of science, biology and life science. It also explains the two terminologies and their characteristics. Biology is a specific branch of science that focuses on the study of living organisms, while life science is a broader term that includes biology and other related disciplines, all trying to decode and explore the complexity of life.

FAQs on Difference Between Biology and Life Science

1. What is the main difference between biology and life science?

Biology is a specific branch of science that deals with understanding the morphology, anatomy, physiology and evolution of a living organism, while life science is a broader field aiming to understand various fields including biochemistry, biophysics, neuroscience, computational and systemic biology, microbiology, and more. The latter often adopts an interdisciplinary approach and integrates knowledge and methods from physics, chemistry, biology, computer science and even statistics.

2. What are the practical applications of biology and life science?

Biology and life sciences have a myriad of practical applications in biotechnological and pharmaceutical industries. Their contribution to understanding the pathophysiology of diseases, developing new treatments, drug design and advancing healthcare in medicine is indispensable. In agriculture, they aid in crop improvement, pest management, and sustainable farming practices. In environmental science, they help in conserving biodiversity, understanding ecosystem dynamics, and addressing climate change.

3. What career options are available in biology and life science?

Researchers, professors, or laboratory technicians in academic and research institutions are a few common career options in biology. They can also work in healthcare, pharmaceuticals, biotechnology, and both governmental and non-governmental conservation organizations. There are also several opportunities in fields such as genetic counselling, bioinformatics, science communication, and science policy.

4. What are some emerging areas of research and advancements in life sciences and biology?

Both these branches of science are dynamic as there are rapid advancements in the ongoing research works in these fields. Some emerging areas of research include genomics and personalized medicine, which aim in developing personalized therapies and drugs with limited off-target effects by studying the individual genome and genetic variation. Additionally, fields like synthetic biology, which combines biology, click chemistry and engineering are gaining prominence as they are revolutionary in terms of expanding the genetic codon. Other emerging areas include neurobiology and neuroscience, where researchers are adopting an interdisciplinary approach to understand the intricacies of the brain and nervous system.
