BIOLOGY
(Code No. 044)
Syllabus for Purpose of Examination 2021-22
CLASS – XI and XII (2021-22)
The present curriculum provides the students with updated concepts along with an extended
exposure to contemporary areas of the subject. The curriculum also aims at emphasizing the
underlying principles that are common to animals, plants and microorganisms as well as
highlighting the relationship of Biology with other areas of knowledge. The format of the
curriculum allows a simple, clear, sequential flow of concepts. It relates the study of biology to
real life through the use of technology. It links the discoveries and innovations in biology to
everyday life such as environment, industry, health and agriculture. The updated curriculum
focuses on understanding and application of scientific principles, while ensuring that ample
opportunities and scope for learning and appreciating basic concepts continue to be available
within its framework. The curriculum is expected to:
promote understanding of basic principles of Biology
encourage learning of emerging knowledge and its relevance to individual and society
promote rational/scientific attitude towards issues related to population, environment and
development
enhance awareness about environmental issues, problems and their appropriate solutions
create awareness amongst the learners about diversity in the living organisms and
developing respect for other living beings
appreciate that the most complex biological phenomena are built on essentially simple
processes
It is expected that the students would get an exposure to various branches of Biology in the
curriculum in a more contextual and systematic manner as they study its various units.
