1.B.Sc. I : Provided syllabus B.Sc. I was read & discussed thoroughly and it has been approved with minor changes. A copy of the syllabus provided with minor corrections is being submitted herewith.

2.B.Sc. II: Provided syllabus of B.Sc. II was also discussed critically & the following changes have been made;

Unit –I: approved as such

Unit-II: Eight families have been deleted, while one family e.i. Asclipi has been included Unit-III: approved as such

Unit-IV: In addition to the course mentioned Unit IVth of (Palynology) of Paper II (B.Sc.-III) have been added as palynology in more befitting at this place.

Paper II: The title of paper is new; Plant Physiology:- This paper has been critically analysed & now it has been fractionated in four units:

The provided syllabus has included biochemistry in paper III which has been shifted to B.Sc. III paper II, become chemistry is more relevant with molecular biology.

B.Sc. III:

The names of papers have been revised as per need & scope of the subject.

Paper I: Plant resource utilization and Biostatics

Paper II: Molecular biology and biochemistry

Paper III: Environment botany and Biochemistry

Paper Ist: Units I, II, III hae been retained as such while a part of unit (IV) e.g. Palyonology- has been shifted to B.Sc. II paper Ist unit IV. E.g. Pollen morphology is closely related to that part.

Paper IInd : Unit I & II have been retained as such while unit 3rd & IV have been shifted to paper III. In place of these units IV of paper III class B.Sc. II (i.e. Biochemistry) has been included at the place of unit III & Unit IV.

Paper III: Unit I, II & III have been maintained as such while unit IV has been replaced with unit 3rd & uth of paper II (B.Sc. III).

Note: Syllabus of B.Sc. I comprising of paper I, II & III is being submitted with minor necessary corrections. It may be considered in the nearly by academic counsil for immediate implementations from the current session. i.e. 2011-12.
