INTRODUCTION

This book aims to meet the latest requirements of the new Hong Kong Diploma of Secondary Education Examination (HKDSEE) Biology Curriculum and Assessment Guide and the changes in emphasis in the examination.

The content of the curriculum consists of two parts, Compulsory and Electives. The compulsory part lays down a solid foundation of knowledge in Biology for students to fields related with Biology. The elective part widens the scope of knowledge and enables students to have choices of topics interested to them. This book covers all the Biology Section 1 of the Combined Science (C.S.). Topics that are not included in the C.S. will be marked with a sign. Further information with advanced concepts is framed by solid lines for the more challenging students.

As in last edition this book is printed in double colours to increase the interest of interest of reading the text and to draw attention to the important terms.

The inclusion of key words to study and misconceptions reinforces learning of the key words and clarifies the correct concepts of certain biological principles.  The concept map helps students build up strong links between the different concepts included in the chapter concerned.  This enables students to relate the different ideas in a more integrated way to get a whole pictures of the topics.

All topics of the past Hong Kong Certificate of Education Examination in Biology are included in the HKDSEE. Analysis of the past papers of the HKCEE gives students an idea about the trend of topics set in the public examination. This is helpful for students to prepare for the HKDSEE.
