Biology ( Chapter-1, 9th Class )
operates under certain principles. For understanding of these principles, the
experiments are done and observations are made; on the basis of which logical
conclusions are drawn. Such a study is called "Science". In brief
science is the knowledge based on experiments and observations.
The Scientific study of
living organisms is called Biology. The word biology is derived from two Greek
words "bios" meaning life and "logos" meaning thought, discourse,
reasoning or study. It means that all aspects of life and every type of living
organism are discussed in biology.
