Unit-I: Plant Physiology
It is the largest unit. It is completely descriptive, understanding unit. It is difficult to understand. More over the lessons are inter related. It carries 28 Marks. It has 6 Chapters. VSA (2), SA (5) and LA (1) type questions are
asked in the model question paper. LA type questions may be asked from Photosynthesis and Respiration. The answers for VSA are difficult to prepare. So care must be taken in preparing the answers. Some times problems may be asked in VSA or SA. The unit almost comprises 1/3 of the total syllabus. Chapters 4 & 5 are the hot spots in Physiology. These two chapters require the knowledge of Chemistry. There is more scope for numerical problems and application type questions.
Unit-II: Microbiology
It has 2 chapters. It carries 6 Marks. There is possibility of 1 VSA & 1 SA type questions. The 2 chapters are full of information and understanding part is very less.
Unit-III: Genetics
It has only one chapter. It carries 6 Marks. One VSA and one SA come from it in IPE. The chapter deals with Mendelian principles. The student must be aware of the terminology in it. It is precise. The terms are specified and should be leant properly. The glossary given at the end of the chapter is useful to follow the lesson. It is a lesson that helps in Biotechnology also. It also requires the knowledge of Chromosomes, Nucleic acids. There is more scope for numerical problems. The student must practice the crosses several times.
Unit-IV: Molecular Biology
It has only one chapter. It carries 8 Marks. There is scope for 1 or 2 VSA and 1 SA (or 2 SA) type questions. The chapter is little difficult to learn. The teacher makes the chapter easy by explaining every word in it. It needs the knowledge from cell biology, biomolecules etc. Though it carries 8 marks in IPE it becomes the hard nut in further entrance examinations. It takes more time to learn. There is more scope for numerical problems. The student has to go through the lesson several times and sit to prepare answers for VSA, SA and Exercises. Glossary helps in understanding. Every definition is to be leant letter by letter. The help of an experienced teacher is essential.
Unit-V: Biotechnology
It has 2 chapters. It carries 16 Marks. One LA, one or 2 SA and 2 or 3 VSA type questions come from it in IPE. This is a unit dealing with modern, recent developments in Biology. Again it is one of the most difficult units. ➠ It requires thorough knowledge of Molecular Biology and Biomolecules. The definitions, glossary should be leant before preparing answers for VSA, SA and LA. There are only 3 LA type questions. So one among them can be asked definitely.
Unit-VI: Plants, Microbes and Human Welfare
It has 2 chapters. It carries 12 Marks. One LA, One SA (or 2 VSA) may come from it in IPE. It is an easy unit. It is descriptive and can be easily understood. The glossary or other terminology can be easily followed. It is actually concerned with general knowledge of modern developments in Biology.
