Meaning of biology as a science of life

Meaning of Biology: the science of life

The term biology comes from the Greek words βίος, bios = “life” and λόγος, lògos = “study”). The meaning of biology is contained in the study of living organisms and their functioning; In fact, it includes the classification of the various forms and examines the complex of phenomena that characterize them from biochemical, physiological, genetic and ecological points of view. Specifically, the meaning of biology relates to the study and analysis of the physical and chemical processes of phenomena that characterize living systems, including biochemistry, molecular mechanisms, genetics, anatomy, and physiology, as well as emerging processes such as adaptation, development, evolution, and interactions between organisms. live and behavior.

Consolidation of concepts about the meaning of biology

Despite the great complexity of the discipline, there are some unifying concepts related to the meaning of biology that organize its study and research: in fact, biology recognizes the cell as the basic unit of life, and genes as the basic structure of inheritance and Darwinian evolution by natural selection as a process that regulates the birth and extinction of species. All living things, unicellular and multicellular, are open systems that live by transforming energy and reducing the local entropy of the system to regulate their internal environment and maintain a stable, energetic state called homeostasis. The meaning of biology is all about research that uses the scientific method to test the validity of a theory in a rational, unbiased, and repeatable manner which consists of forming hypotheses, experiments, and later analyzing data to prove the validity or invalidity of a scientific theory.

characteristics of biological systems

Each living organism has a set of characteristics that distinguish it from a non-living organism. The meaning of biology is attached here!

Some of the main features are listed below:

• Living things are made up of cells
• Living things grow and develop
• Living things reproduce
• Living organisms regulate their own metabolism
• Living organisms perform delicate reactions to ensure homeostasis
• Living things respond to stimuli
• Living things possess genetic information
• Populations of organisms are subject to evolution

The key to the differences between living things and non-living things is organization. Every organism is made up of different parts which co-operate harmoniously: therefore it follows a strict organization. Maintaining orderly structures requires a high demand for energy, and it is precisely the energy in which the secret of life, as well as the meaning of biology, is concentrated.

Foundations of Biology

The primary aspect that distinguishes a living organism from an inanimate object is the ability to reproduce by generating other organisms with the same basic characteristics, which are controlled by a genetic program. The importance of biology as a science of life is concentrated here. Living organisms are constantly undergoing transformations, that is, chemical reactions, to which the activities essential to sustaining life return. Among them are the production of energy for muscle movement, the digestion of food, as well as the production of substances secreted by glandular cells. The life of living organisms themselves depends on these chemical reactions: in fact, if they stop, cells and organisms die within a few moments.

Degree in biological sciences

the A three-year degree course The Master’s Program in Biological Sciences aims to train a professional figure who is able to deal with the problems of modern society that have a great impact on human life as well as on the various organisms that inhabit the Earth. It also aims to provide a solid foundational knowledge in the main areas of employment and investigation of the meaning of biology in all its forms. It seems suitable for subsequent in-depth studies and specializations also with access to second-level university studies in the biological field (master’s or master’s degree).

CdL educational objectives in the biological sciences

The degree course aims to provide a strong foundational knowledge of the main sectors of the biological sciences. Studies are concerned with deepening the meaning of biology as an investigation of theoretical and experimental aspects that are useful for inclusion in work activities and that require mastery of the scientific method. The study paths allow male and female students to develop a good mastery of the methodologies and techniques inherent in the relevant fields of scientific research, with the aim of carefully understanding the meaning of biology, offering above all an adequate preparation for the assimilation of scientific and technological advances and for the correct knowledge and treatment of organisms.
