CHAPTER ONEINTRODUCTION1.1 Background of the StudyScience is a systematic study of the universe and natural process there (Kalu, 2017). No nation can afford to neglect science education at any level and hope to thrive in any field of human endeavour (Olatoye, 2017). The term Biology is derived from two Greek words “Bios” and “Logos” which means “life” and “study”, respectively (Adeogun, 2011). Biology is the study of living things (plants and animals). Biology engages the people to understand the world around them and so have the ability to make informed choices about their healthcare, the environment and the society in which they live (Ihejiamaizu and Ochui, 2016). It has become the central intellectual discipline especially in the aspect of biotechnology and indispensable in helping individuals to think more clearly about the values involves in the fast changing world.Biology as a separate science was developed in the nineteenth century as scientists discovered that organisms shared fundamental characteristics (Arokoyu and Chukwu, 2017). Biology is a subject of instruction at schools and universities around the world and over a million papers are published annually in wide array of biology and medical journals (Christyl, 2011). Ambuno, Egunyomi and Osakwe, (2018) stated that Biology forms the basis of disciplines like human medicine, veterinary medicine, Nursing, Agriculture, forestry, fishery, pharmacy, food technology, laboratory science Technology, biological weapons and human nutrition to mention just a few. Most biological sciences are specialized disciplines. Traditionally, they are grouped by the type of organism being studied: botany (the study of plants); zoology (the study of animals); and microbiology (the study of microorganisms). The fields within biology are further divided based on the scale at which organisms are studied and the methods used to study them.
