How To Learn Biology :: What Is Biology 101

The term "biology" is derived from the greek words;

/bios/ meaning /life/ and

/logos/ meaning /study/

The definition of biology is simply the science of life and living organisms. An organism is a living entity consisting of one cell e.g. bacteria, or several cells e.g. animals, plants and fungi.

And from our friend: Wikipedia

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. Modern biology is a vast and eclectic field, composed of many branches and subdisciplines.

So What Is The Meaning Of Biology?

UPDATED:  

Aspects of biological science range from the study of molecular mechanisms in cells, to the classification and behaviour of organisms, how species evolve and interaction between ecosystems. As you can see, there are many aspects of biology to be explored and "investigated".

The study of biology can be divided into different disciplines –

  • Ethology
  • Evolutionary Biology
  • Physiology
  • Genetics
  • Molecular Biology
  • Morphology
  • Systematics
  • Ecology

When trying to define biology, one must consider that it often overlaps with other sciences; for example, biochemistry and toxicology with biology, chemistry, and medicine; biophysics with biology and physics; stratigraphy with biology and geography; astrobiology with biology and astronomy. Social sciences such as geography, philosophy, psychology and sociology can also interact with biology, for example, in administration of biological resources, developmental biology, biogeography, evolutionary psychology and ethics. Check out our biology book section for further information on these particular biological sciences.

Learn All About Biology Selection Of YouTube Biological Educational Video Clips


Below we have compiled a selection of biology educational videos on a range of simple biology areas as it does tend to branch out in many different directions offering vast opportunities. If you are wanting a more comprehensive instructional presentation, please see our biology videos section.

The first presentation runs for approximately 52 minutes and provides a thoruough overview of biology as it relates to the microscope, slide, cultures, staining and further explainations. It contains common industry usage of the microscope and their purposes including terminology as used in mircobiology.

There are also industry professionals explaining various aspects of biology, teachers, lecturers and others employed in biology related fields covering all you need to know as an introduction to biological related studies and occupations. You will note that the humble compound microscope features heavily in all facets of biology science and research.

There are many different facets of science and biology, hopefully these videos on an introduction to biology will help with your microscope selection requirements aswell as learning some more about what biology is all about.
