The WBCHSE Class 12 Biological Science syllabus is structured to provide a strong foundation in both plant and animal biology. The curriculum covers essential topics such as human physiology, reproduction, genetics, evolution, ecology, plant physiology, and biotechnology. Human physiology includes a detailed study of the digestive, respiratory, circulatory, excretory, and nervous systems. Understanding these processes develops a conceptual clarity that is essential for medical, environmental, and research-oriented careers.
Genetics and evolution form a critical part of the syllabus, focusing on principles of inheritance, DNA structure, and natural selection. Ecology and environmental biology emphasize conservation, biodiversity, and sustainable practices, fostering environmental awareness among students. Plant physiology covers photosynthesis, respiration, transport systems, and plant growth regulators, helping students understand fundamental life processes. Biotechnology introduces students to modern techniques such as genetic engineering, tissue culture, and cloning, bridging classical biology with applied science. The WBCHSE syllabus encourages practical learning through laboratory experiments, project work, and diagrammatic representation, enabling students to develop observation and analytical skills. A well-planned study schedule and consistent practice are essential for excelling in both theory and practical examinations.
