Class 9th Biology Chapter 1 Notes MCQ’s, Short Answers and Long Questions
Science is the systematic study of nature through observations, experiments, and logical deductions. In ancient times, scientific knowledge was unified under the umbrella term “science,” but with the growth of knowledge, it was classified into various branches such as biology, physics, chemistry, and mathematics. Biology, derived from Greek words meaning “life” and “thought,” is the scientific study of living organisms and their functions.
It encompasses divisions like Zoology (study of animals), Botany (study of plants), and Microbiology (study of microorganisms). These divisions further branch out into specialized areas like Genetics, Anatomy, Physiology, and more. Through biology, we understand nature and find solutions to human health, food, and environmental issues, making scientific knowledge a shared heritage.
