Science is a great enterprise which nations depend on, in-order to advance technologically. Science therefore, is receiving much emphasis in education because of its significance and relevance to life and society. Science is both a process (scientific method) and a product (knowledge, fact and principles) (Ezeh, 2013). Both the process and product of science are acquired through education and this is specialized type of education such as science education. Science plays important roles in the society because it relates to our daily life and career. The importance of science in our society made the Federal Government of Nigeria, through the Federal Ministry of Education to introduce science subjects in the nations secondary school curriculum. Biology is one of such subject introduced.
Biology is defined as the study of life and structure of living things. Biology is the study of living things and concerns itself with the study of the structural, behaviour, distribution, the origin of plants, and animals and their relationship with their environment (American Heritage Dictionary of the English Language 2009). Abugu (2007) stated that biology is natural science in which we study living organisms plants and animals. The knowledge of biology helps in checking environmental degradation such as desertification, erosion, water hyacinth, land, air and water pollution.
