CHAPTER 1 : THE SCIENCE OF BIOLOGY

1.0 Introduction

Biology is the science devoted to the study of living objects. Two Greek words, bios (life) and logos (discourse), explain the term "biology" as meaning study of living creatures. Since life manifests itself in various forms i.e. plant and animal forms, biology is the study of both. The study of plants is termed as botany or plant biology, while the study of animals is called zoology or animal biology.

Biology also comprises of the cellular basis of living things for the activities of life. It consists of energy metabolism and also of genetics which forms the basis of inheritance in organisms. Living things have been studied since primitive times. Primitive man had to find out what could be utilized for food, shelter and clothing, which plants would be useful as medicines and which animals he could use to get work done for him. The science of biology thus arose out of basic human needs.


Biology also includes evolutionary relationships between organisms. Biology tells us about the routine activities of microorganisms, plants and animals and also the relation between their structures and functions. Many sub-divisions and special areas of biology exist but biology can conveniently be divided into two categories, (A) Practical and (B) Theoretical.

  • Practical biology consists of plant breeding, medical science, wildlife management, agriculture.

  • Theoretical biology consists of Physiology (the study of the functions of living things), Microbiology (the study of microscopic organisms), Biochemistry (the study of the chemical makeup of organisms), Ecology (the study of populations and their environment) and Taxonomy (categorization).
