Definition of Biology – What is Biology?
Biology is a branch of science that deals with the study of living things.
? There are diverse forms of life on earth ranging from the invisible
microscopic living things to the gigantic life forms. It aims at
explaining the living world in terms of scientific principles.
? It is important to note, however, that living things interact with the
non living things in the environment as well.
? Biology, therefore also entails the study of non living things as well.
The role of human beings in shaping the environment is also
investigated in biology.
? In summary, biology deals with the study of origins, types, nature,
growth, development, interactions and maintenance of all life forms
on earth.
Importance of biology
The study of biology is very important. The knowledge acquired from this
study can benefit an individual in myriad ways. The study of biology is
important in that:
The knowledge acquired from the study of biology can be very helpful
in solving environmental problems such as food shortage, poor health
services, pollution and environmental degradation.

The study of biology can grant one an entry into various careers such
as medicine, veterinary medicine, animal husbandry, horticulture
and dentistry.

The study of biology leads to development of scientific skills which are
very useful in life. These include skills of observing, identifying,
recording, classifying, measuring, analyzing and evaluating. These
skills can enable one learn how to make right choices and lead an
improved life.

Through the study of biology man learns the causes of human, plant
and human diseases and how best these diseases can be prevented and
cured.

Biological knowledge acquired in the study of biology is very useful in
enhancing international cooperation. Some biology related
international conventions include:
