Life sciences

The Life Sciences are a broad field of science dedicated to the study of all aspects of living organisms and their interactions with the environment. This encompasses a range of disciplines that explore the structure, function, growth, origin, evolution, and distribution of living organisms. From the microscopic level of cells and genes to the complex systems of ecosystems and global biodiversity, the life sciences aim to unravel the mysteries of life.

Branches of Life Sciences[edit | edit source]

Biology - The core discipline that studies living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development, and evolution.
Biochemistry - Explores the chemical processes within and related to living organisms.
Botany - The study of plants, including their physiology, structure, genetics, ecology, distribution, and classification.
Zoology - Focuses on animals, examining their anatomy, physiology, genetics, behavior, and ecological roles.
Microbiology - Investigates microorganisms, including bacteria, viruses, fungi, and protozoa.
Genetics - The study of genes, genetic variation, and heredity in living organisms.
Ecology - Examines how organisms interact with each other and their environment.
Evolutionary biology - Investigates the processes that produced the diversity of life on Earth, including natural selection and genetic drift.
Neuroscience - Explores the structure and function of the nervous system and brain.
Pharmacology - The study of how drugs interact with biological systems.
Physiology - Investigates the physical and chemical functions of organisms, including humans.
Biotechnology - Applies technology to the biological sciences for practical applications, such as genetic engineering and drug development.

Glossary of Life Sciences Terms[edit | edit source]

Cell (biology) - The basic structural, functional, and biological unit of all known living organisms.
DNA (Deoxyribonucleic Acid) - A molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.
Ecosystem - A community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.
Gene - A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
Biodiversity - The variety and variability of life on Earth, including the diversity of species, genetics, and ecosystems.
Photosynthesis - A process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
Homeostasis - The ability of an organism or environment to maintain stability in spite of changes.
Mutation - The changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations.
Natural Selection - The process whereby organisms better adapted to their environment tend to survive and produce more offspring.
Pathogen - A bacterium, virus, or other microorganisms that can cause disease.
Biome - A large naturally occurring community of flora and fauna occupying a major habitat, e.g., forest or tundra.
Chlorophyll - A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
