BIOLOGY
SYLLABUS FOR HIGHER SECONDARY FIRST YEAR COURSE

The present syllabus reinforces the ideas introduced in the lower classes while the students learn
new concepts besides getting an exposure to contemporary areas of the subject. The syllabus also aims
at emphasizing on the underlying principles which are common to both animals and plants as well as
highlighting the relationship of biology with other areas of knowledge. The format of the syllabus allows
a simple, clear, consequential flow of concepts without any jarring jumps. The syllabus also stresses on
the connection of the study of Biology to real life problems, use of biological discoveries/innovations in
everyday life- in environment, industry, health and agriculture. The updated syllabus also focuses on
reducing the curriculum load while ensuring that ample opportunities and scope for learning and appreciating
basic concepts of the subject continue to be available within its framework.
The prescribed syllabus is expected to
 Promote understanding of basic principles of biology
 Encourage learning of emerging knowledge and its relevance to individual and society
 Promote rational/specific attitude to issues related to population, environment and development
 Enhance awareness about environmental issues and problems and the appropriate solutions
 Create awareness amongst the learners about variations amongst the living, and developing respect
for the diversities and to appreciate that the most complex biological phenomena are also built on
essentially simple processes.
It is expected that the students would get an exposure to various branches of Biology in the
syllabus in a more contextual and friendly manner as they study its various units.
