This book has been prepared with an idea that on completion of
the course, the student can opt for any field related to the Biological
Sciences in his / her higher studies. A foundation for learning various
subjects had already been provided in the lower classes through
appropriate revisions in the syllabus. The revision of syllabus made,
has provided us with an opportunity to offer adequate information
related to several fields in biology to the students of Higher Secondary
classes. The 11th and 12th standard lessons are interlinked. A sound
knowledge of the material provided in this book will be essential for
pursuing the next level.
The lessons are written in such a way that the student is
encouraged to do further reference work. A list of books for such
reference work is provided. The students can also visit websites related
to each lesson.
Sample questions are provided at the end of each unit. The
teachers can frame more questions to test knowledge, understanding,
application and extension of this discipline.
As the scope of life sciences is widening due to increasing
demands and ultra developments in all fields, an active, interested
indulgence in the study of Biology will certainly be beneficial.
