The word biology is derived
from the greek words /bios/ meaning /life/ and /logos/ meaning /study/
and is defined as 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. 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.
The study of biology can be divided into different disciplines
Ethology
Evolutionary Biology
Physiology
Genetics
Molecular Biology
Morphology
Systematics
Ecology
Biology
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.
