First of all, thanking the CREATOR who bestowed me to bring out the book ‘Biology-X Instant notes’ to the students of class X under Kerala state syllabus. This book has been exclusively designed as a powerful tool for the last-minute preparation in their pursuit of success in the SSLC-Board Examination. Every effort has been made to make the description point wise as per the new grading and evaluation system. Difficulties which nerve the students have been dealt within simple and lucid style. I hereby express my sincere gratitude to Rahees Valappil (Director, Sunrise InstitutePandikasala) who put forward the idea of making capsule notes, Vinod Sir (G.Rajas.H.S.S, Kottakal) & Jaleel Sir (Oriental H.S.S, Tirurangadi), who ready to share their valuable materials, My brother, Munawar Ahammed, who helped me in typing material and all and all Rajeev Sir (Blogger, www.english4keralasyllabus.com) who constantly motivated me in bringing this note. I kindly requesting the teaching faculties to share their materials with English blog, who humbly trying to give as much aids to the student community. I hope that this book will be warmly received by students and teachers. Great care has been taken to avoid mistakes. Constructive criticism of the book and suggestions for its further improvement will be gratefully acknowledged.
