Neuberg introduced the term biochemistry in 1903. The early part of 20th century witnessed a sudden outburst of knowledge in chemical analysis, separation methods, electronic instrumentation for biological studies (X-ray diffraction, electron microscope, etc) which ultimately resulted in understanding the structure and function of several key molecules involved in life processes such as proteins, enzymes, DNA and RNA . Scope of Biochemistry 1) To evaluate ( मूल्यांकन करना ) nutritive value of cereals, pulses, oilseed, fruits and vegetable. 2) Formulation of balanced diet. 3) Removal and inactivation of toxic or anti nutritional factors present in food grains in general and grain legumes in particular by breeding and chemical treatments. e .g. ODAP in Keshari dal, Trypsin inhibitors. 4) Development and exploitation of better genotypes. 5) Food preservation and processing technology and post-harvest physiology of fruit crops and vegetables and their nutrit...

Bryophytes • Bryophytes include the various mosses and liverworts that are found commonly growing in the most shaded area in hills. It is also called Amphibians of the plant kingdom. Water for sexual reproduction. It plays important role in plant succession on bare rocks / soils. Root – like, leaf – like or stem – like structure. \the male sex organ is called antheridium. They produce biflagellated antherzoids. The female sex organ archegonium is flask – shaped produces a single eggs. Zygote do not undergo reduction division immediately. Species of Sphagnum, a moss , provide peat. Mosses along with lichens one the first organisms to colonise rocks. Great ecological importance. Reduce the impact of falling rain and prevent soil erosion. The Bryophytes are divided into liverworts and mosses. Live...
