11th Class Biology The Living World / जीव जगत Scope of Biology

Biology creates an awareness of vast array of forms of life which normally goes unseen. Biology offers a large scope and provides a large field for study.

(1) Helps us to understand ourselves better : It unfolds different queries of life alongwith its cultural, social, philosophical and economical aspects. So it helps in understanding the life better.

(2) Biology and inter-relationship of living beings : Study of biology helps us in understanding the wonderful phenomenon and laws of nature which finally tell us to predict the behaviour of different living beings under changed conditions.

(3) Biology and resources : Biology helps us to know how to tap and conserve the resources available to us e.g. fishes, birds, forests etc.

(4) Biology and literature : Knowledge of Natural Biology has greatly enriched the literature with their references in stories and poems etc. Poets and other authors have been inspired by the beautiful and interesting plants and animals and frequently figure them in stories, poems and dramas.

(5) Study of nature is a rewarding experience : Many plants like Narcissus, Dahlia, Gloriosa, Roses, Marigold, Aster, etc. are used for ornamental purposes. The variety available in animals is widely enjoyed in zoological parks. Students enjoy excursions to remote places watching never seen before plants and animals.

(6) Solving problems : Biology makes us to understand the present day problems such as population growth, pollution, conservation of wildlife and survival of man etc. The future directions of biotechnology, conservation of biodiversity, maintenance of environment  and human welfare remain in the hands of biologists.

(7) Biology-Medicinal aspect : Several plants like Atropa belladona, Cinchona are sources of atropine, quinine etc. Many members of fungi such as Penicillium and Streptomyces give rise to antibiotics like penicillin and streptomycin. Plants are the major source of vitamins. Drugs are first tested on animals before being used for treating man. Animals provide scientific hints for the production and use of medicines. Animals are widely used for scientific research and results thus obtained are finally applied to man. The study of animal play an important role in health, nutrition and control of pests. Many diseases like malaria are caused and transmitted by animals.

(8) Solving approach of biology : Knowledge for eradication of diseases like malaria, small pox, etc. have been achieved by scientists basically due to desire and determination to solve the problem.

(9) Ecosystem and living organisms : Biology helps us in understanding the various ecosystems. The living community and non-living environment interact with each other and exchange of material in them takes place.

(10) Biotechnology : Biotechnologists have produced many genetically modified (GM) crops. Plenty of studies are being made by geneticists, evolutionists and cytologists to fudge the efficacy of biotechnology.
