Life Science

The life sciences include the areas of science which entail the scientific research of living organisms, such as plants, animals, as well as human beings. Although biology stays the focal point of the actual life sciences, technical advances within molecular biology and also biotechnology have brought to a growing of special areas of practice and new, usually interdisciplinary, areas.

Curiosity of man about himself and his surrounding gave birth to various branches of scientific study. Life science of biology must have been born very early during the past, as man was eager to find out about the living world.


Scope of Life Science

The scope of life science is quite vast. Recent advancement in technology has helped biologist to gather more information about the living world. Several applied branches in biology have helped man in his day to day life.

Man is completely dependant on plants and animals for food. Microorganisms provide us with various kinds of fermented foods such as curds, cheese, butter, etc. Understanding life science in depth helps us to improve the ways of procuring food from plants and animals. With knowledge of biotechnology man has produced genetically modified (GM) crops. These are supposed help us to overcome the food shortage problem in the world.

Plants supply us material for clothing, shelter, making furniture etc. Study of biology has helped us to extract various oils, resins and other plant secretions for commercial use. Several industries turn out finished products from raw materials taken from plant and animal sources.

Branches of Life Science

The life science of biology is so vast and extensive that biologists have divided it into several branches for convenient study. These branches are grouped into three main categories-classical branches, interdisciplinary branches and applied branches.


Categories-Classical branches of Life science

• Anatomy – The study of internal structure of organisms (animals and plants).
• Physiology – The study of various body functions of organism such as nutrition, growth, respiration, excretion etc.
• Genetics – It is the study of heredity and variations. It is the branch of biology which deals with the study of transmission of characteristics from the parents to the offspring’s.


Interdisciplinary branches of Life science

• Biochemistry – It is an interdisciplinary science which has emerged to consolidate the knowledge of organic chemistry and biology. Biochemistry deals with the chemistry of biological processes which helps us to understand various biochemical processes in respiration, photosynthesis, protein synthesis, etc.
• Biophysics – It is the application of the knowledge of physics in the field of biology which helps us to understand the physics of life processes.
• Biostatistics – It deals with the collection, classification and tabulation of numerical facts for explaining, describing and comparing the biological phenomena.


Applied branches on Life science

• Agriculture – Agriculture deals with cultivation of crops, care of soil and raising of livestock. It is a branch of applied biology. Agriculture life science provides information on various aspects of production, processing, marketing and distribution of agricultural products like oil seeds, pulses, cereals, cotton, sugarcane etc.
• Pathology – The life science dealing with the nature, causes, symptoms, effects, prevention and suggestive curing of disease is pathology. Pathology is a specialized field for the diagnosis of diseases in medical science, veterinary science, agriculture and forestry.
