This book, tutorials for practice , is written to help the students to know the concept better. It is based on the new pattern of syllabus set up for all India entrance test for medical students. This book included only a few selected topics which the students find most difficult, like biodiversity, Biocatalyst, respiration, photosynthesis, DNA recombinant technology, homeostasis, population and ecology, Ecology, gaseous exchange and its control, transport system, co-ordination and immunity. Each chapter is subdivided into three categories, the first section –A, dealt with MCQ to know the understanding of the basic concept ofthe topic, the section B is related with structural questions to know the memory status of the students relating to the concept and the third section C is designed to know the in-depth knowledge and its presentation power by asking essay type questions. I hope that students will enjoy this book and will get better concept clarification relating to the hard and most tough topics in biology. - See more at: http://pothi.com/pothi/book/dr-ashokan-kannarath-tutorials-practice#sthash.1ththcGk.dpuf
