INTRODUCTION TO
BIOLOGY
Now a days we find contributions of Aristotle, Socrates,
Theophrastus and many other scholars of the past age in different fields of
knowledge. This is not possible for the scholars of the present time. A
question may arise in your mind as to why it is not possible today. The reason
is that in ages long past the extent of knowledge was limited. People engaged
in achieving knowledge were also small in number. Today the dimension of
knowledge has been increased many times. To contribute in more than one field
is quite difficult at the present time. For convenience to know and understand
things we have divided our world of knowledge in many branches. In this way
Science, Literature, Arts, Social Science and many other branches have been
created. As a whole, knowledge of human beings is undivided. But it has been
divided into various branches for easy learning and understanding.
You may have known that the knowledge of science is
increasing rapidly. It is becoming possible because of the research of a large
number of scientists in different fields of science. Many people think that
knowledge of science is becoming double in every eight years. New subjects of
science are being created. It is not possible to realize and understand this
huge store of knowledge for an individual alone. As a result, scientists are
engaged in research in particular subject or topic. At different times many
scholars have divided the knowledge of science in various ways. The division
and different branches of science are constantly spreading with the increase of
knowledge in science. The two main branches of science are Physical science and
Biological Science.
Physical Science is otherwise called the Science of
non-living things. In Physical science characteristics, actions-reactions,
multiformaity and many similar other properties of non-living objects are
examined and discussed.
Observation, examination and discussion of livings beings
are included in Biology. Biology is the science of living beings. The term
Biology comes from two Greek words (bios means life and logos means knowledge).
Aristotle is regarded as the father of Biology.
We find two types of life in nature. One is plant while
the other is animal. Accordingly Biology has been divided into two branches:
Botany and Zoology. Botany deals with theoretical discussion and research about
characters and other features of plants, while Zoology is limited in subjects
relating to animals.
