Life sciences quite literally refer to the study of living organisms, such as plants, animals, human beings and microorganisms.
Biology is the natural science concerned with studying life and living organisms, life sciences being its sub-disciplines, which normally have their own focus. For example, zoology studies animals and botany is the study of plants. Anatomy and genetics are also considered life sciences, as they also focus on common aspects of life.
Some life sciences go as small as being concerned with the microscale, with molecular biology and biochemistry falling into the category, and on larger scales, cytology, immunology, ethnology and ecology. A major part of life sciences is understanding the human mind, or in other words, neuroscience!
Other branches of life sciences are as follows: anatomy, toxicology, histology, astrobiology, biophysics, bio-linguistics, quantum, structural and population biology, immunology and many more.
All in all, life sciences are used to study and improve the quality of life, for human, animals and plants, whether that is through advancement in agriculture, medicine, health and the food industries.
