1.1 Background to the Study
Biology is a branch of science that studies life. According to Maduabum (2006), science (Biology) constitute the bedrock of the National development which in its broadest sense refers to all human activities which involves organized knowledge of natural phenomena. It simply implies that, science is the systematic study of nature with the purpose of accumulating an organized body of matter, their interaction and outcomes. Omiko (2011) sees science as the way of knowing the facts and theories of the nature. According to him, this knowledge of facts and theories promote attitudes of reality, objectivity, curiosity, self-examination and search of truth.
Eweleukwa (2005) defined biology as a science subject that deals with life. It was derived from two Greek words: “Bios” which means life and “logos” which means study. Biology therefore means the study of life or living things. Ekwu (2012) defined biology as a natural science which deals with the study of living organisms. According to him, it is derived from two Greek words “Bios” which means life and “logos” which connotes knowledge. It is a fascinating study that ranges from microscopic cellular molecules to the biosphere, encompassing the earth’s surface and its living organisms.
The oxford advanced learners dictionary defined biology as the scientific study of life and structure of plants and animals. Taylor (2012) defined biology as a science devoted to the study of living organisms. As a natural science, biology is the individual life forms within the world of life known as nature. Biological studies cover all that is known about plants, animals, microbes, or other living things of the past and present. It is the science of fishes, grasses, flies, grasshoppers, humans, mushrooms, flowers, sea stars, worms and moulds. In fact, biology is the study of the life on top of the highest mountains and at the bottom of the deepest sea.
William (2012) stated that at different levels of education, all learners are exposed to the following levels of biological organization: cellular level, molecular level, tissue and organ level, the community level and the world biomes. Biology programmes prepare students for several fields of life such as: agriculture, medicine, veterinary science, dentistry, food production industries, horticulture, biochemistry, biotechnology and teaching.
