Definition
Life sciences are the sciences that study living things, from cells to ecosystems. They include biology, zoology, botany, and ecology (Credits :Gooogle Search Engine)
Life science disciplines
Biochemistry
Biochemistry explores chemical processes related to living organisms. It is a laboratory-based science combining biology and chemistry. Biochemists study the structure, composition, and chemical reactions of substances in living systems and, in turn, their functions and ways to control them.
There are four classes of biochemical compounds: carbohydrates, proteins, lipids (fats), and nucleic acids. We get these from our food.
Microbiology
Microbiology is the study of the biology of microscopic organisms – viruses, bacteria, algae, fungi, slime molds, and protozoa. The methods used to study and manipulate these minute and mostly unicellular organisms differ from those used in most other biological investigations.
Branches of Microbiology
- Bacteriology- The study of bacteria.
- Mycology –The study of fungi.
- Phycology- The study of photosynthetic eukaryotes. ( …
- Protozoology – The study of protozoa (Single-celled eukaryotes)
- Virology- The study of viruses, non-cellular particles which parasitize cells.
- Sustainable Microbiology is driven by seven core principles including sustainability, reliance on renewable resources, biodegradability, multifunctionality, biocompatibility, diversity, and collaboration between experts, policymakers, and the end users of products that rely on the concept
Molecular biology
Molecular biology is the branch of biology that studies the molecular basis of biological activity. Living things are made of chemicals just as non-living things are, so a molecular biologist studies how molecules interact with one another in living organisms to perform the functions of life.
Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules.
Biotechnology
Biotechnology is technology that utilizes biological systems, living organisms or parts of this to develop or create different products.
the five branches into which modern biotechnology is divided — human, environmental, industrial, animal and plant — help us fight hunger and disease, produce more safely, cleanly and efficiently, reduce our ecological footprint and save energy.
Neuroscience
Neuroscience, also known as Neural Science, is the study of how the nervous system develops, its structure, and what it does. Neuroscientists focus on the brain and its impact on behavior and cognitive functions.
Developmental neuroscience describes how the brain forms, grows, and changes. Cognitive neuroscience is about how the brain creates and controls thought, language, problem-solving, and memory. Molecular and cellular neuroscience explores the genes, proteins, and other molecules that guide how neurons function.
Importance of Life Sciences
Studying the life sciences will provide you with a foundation of scientific knowledge and ways of exploring the world. The life sciences pervade so many aspects of our lives – Ecosystem, health care, the environment.
An ecosystem is a community of living organisms (plants, animals and microbes) in a particular area. The term `eco’ refers to a part of the world and `system’ refers to the co-ordinating units. An ecosystem is a community of organisms and their physical environment interacting together.
Life sciences help us understand ecosystems by studying how organisms interact with their environment. The study of life sciences includes ecology, which is the study of how organisms interact with their environment.
