Life sciences can be described as the sciences that deals with the organisms such as animals, plant and human beings that assist encompasses the companies in the field of food processing, nutraceuticals, life system technologies, and bio medical technologies, biomedical and environmental devices. In short, life sciences deals with the scientific study of the living things that incorporates several levels of investigation ranging from the study of the organic molecules interaction of plant and animals with their environment. There are various reasons associated with studying life sciences such as development of ability to critically evaluate the scientific processes and issue. Studying life sciences also helps in greater awareness of the ways in which the humankind is benefitted from the knowledge of life sciences. The knowledge of key biological concepts, system, process and theories is increased by enrolling in the course of life sciences. Students studying life sciences would be exposed to the scope and ranges of biological studies that helps in creating awareness of possible specialities along with stimulating their interest in it. It helps them in knowing how the environment and the organisms living in it have been negatively impacted by the humans. Furthermore, the ways of thinking scientifically is enhanced by the development of scientific skills which would enable the students to see the flaws in pseudo-science.

Some of the various branches of life sciences include biotechnology, biochemistry, anatomy, ecology, botany, microbiology, generics, medicine, environmental studies, entomology, morphology, microbiology, taxonomy, physiology, socio-biology and zoology. Taking up the course of life sciences study would provide several opportunities for the students and they can take the profession such as animal scientist, agronomist, developmental biologist, biochemist, geneticist, ecologist, developmental biologist, geneticist, food scientist, horticulturist, medical nurse or doctor, marine biologist, microbiologist, medical illustrator, science writer, nutritionist, pharmacologist, palaeontologist, zoologist and veterinarian.

Undertaking the life sciences study comes with some specific objectives such as new knowledge acquisition, understanding the life sciences application in everyday life and investigation of phenomenon.

ü Investigation of phenomenon- This involves gaining an experience in practical work, science experiments and investigation.

ü New knowledge acquisition- A new understanding of processes, life sciences concepts, principles, mechanism, phenomenon, models, law, theories and principles will be acquired when studying the life sciences subject. A connection between fields and topics will be viewed and would learn to analyse and evaluate the things learned.

ü Understanding life sciences application in everyday life- The way science is applied to everyday life would gained along with the understanding of the relationship between science and indigenous knowledge and the history of scientific discoveries.

In life sciences, diagrams and drawings are the essential part of the communication and it is the clear representation of the things observed and the diagrams are used to interpret that is being seen. However, there are few rules that has to be followed while drawing such as the diagram should be drawn in sharp pencil for smooth and clear lines, two dimensional, middle page, specification of the section, indicating the scale of drawing or magnification, stating the diagram or drawing source and drawing label lines. Furthermore, it is important to have mathematical skills in life sciences and some skills that would be encountered by the learner involves averages, scales, conversions and percentages. At the end of each calculations, it is required to state the units.

Life sciences comprises of a number of specializations and different fields and the field of work forms the basis of the basis of the duties of life scientists. Nevertheless, regardless of this area of study, some core responsibilities must be shared by all life scientists. There is a variation in the employment outlook of the life scientists depending upon the education level, geography, field of practice and other factors. Studying life sciences offers a gateway to uncover the living being mysteries and it has paved way to career for the individual that is dynamically successful due to recent scientific advancement. Students who are passionate about the life sciences subjects can have a successful career. However, it requires academic knowledge and qualifications. In addition to this, student can have post-graduation, graduation and diploma along with doctorate degrees for specialization in various fields. All the life scientist can become any scientist of which the centre of work relies on studying living things whether animals, plant, human and bacteria.  

Individual will most likely be working in the hospitals, academic institutions, labs, pharmaceutical companies and clinics if they pursue a career in the life sciences. Scientist working in the arena of life sciences are employed in several different roles. In addition to this, individual could become a clinical biochemist and they would spend their time analysing saliva, blood, semen and samples of urine. They can also become embryologist where such individuals would assist people facing infertility problems using IVF treatment.  They could be also involved in determining the cause of death by working as a pathologist and investigating the hereditary diseases if they become cytogeneticist.  Furthermore, individual could also develop their career as immunologist who conduct studies relating to immune system such as transplant rejection, AIDS, transplantation and various other problems. Nevertheless, individual can also work as technician in the laboratory by providing support to the other clinical scientists having a relevant HNC and HND or to the people who are slightly at junior level.   

As a life scientist, the day to day responsibilities varies depending on the area of specialism. Irrespective of the line which is chosen to be pursued, majority of time spend would be allotted to overseeing and conducting clinical experiments. The findings would be analysed and the conclusions will be presented to the colleagues, peer and medical professionals. It might also be required to attend seminars and conferences along with presenting the research paper to the scientists. Majority of scientists have a degree in the subject of relevant medical sciences such as bio technology, pharmacology, and microbiology and bio chemistry. The minimum educational requirement for working in the field of life sciences is bachelor degree in related area of subject and positions involving education or research that may require Phd degree.
