Biological Science Syllabus for WB SLST 2025 (Class XI-XII)

This syllabus covers comprehensive topics in Zoology, Botany, and Physiology designed to prepare students for the WB SLST examination with a focus on conceptual clarity, practical understanding, and examination relevance.

Zoology

• Invertebrates : Classification and study of animals without backbones, including their organ systems, modes of reproduction, nervous and vascular systems. Emphasis on understanding diversity and adaptations.
• Chordates : Study of vertebrate animals from fish to mammals. Focus on the structure and function of the heart, brain, sensory organs, and skeletal system.
• Cell and Developmental Biology : Detailed study of cell organelles, molecular biology of DNA and RNA, and the process of protein synthesis. Embryology covering chick development and placental formation.
• Evolution and Systematics : Concepts of the origin of life, Darwinian theory of natural selection, species formation, and principles of biological classification and nomenclature.
• Ecology and Biodiversity : Energy flow in ecosystems, population dynamics, conservation strategies, migration patterns, and identification of biodiversity hotspots in India.
• Parasitology and Immunology : Study of common parasitic diseases such as malaria and filaria, and the immune system including T cells, B cells, and macrophages.
• Genetics and Molecular Biology : Understanding blood groups, gene concepts, DNA replication, polymerase chain reaction (PCR), and types of mutations.
• Animal Physiology : Functional study of organs such as lungs, kidneys, and brain. Emphasis on hemoglobin function, enzyme activity, and nerve signal transmission.

Botany

• Cell Biology : Types and structures of plant cells with emphasis on their functions.
• Anatomy : Study of plant tissues, root and stem growth patterns, and their physiological significance.
• Ecology and Environment : Topics include global warming, acid rain, and principles of sustainable living to promote environmental awareness.
• Plant Groups : Classification and characteristics of algae, fungi, bryophytes, gymnosperms, and flowering plants.
• Plant Pathology : Identification of common plant diseases and methods for their control and prevention.
• Taxonomy : Flower classification systems, International Code of Botanical Nomenclature (ICBN) rules, and herbarium techniques.
• Plant Physiology : Processes such as photosynthesis (C3 and C4 pathways), respiration, plant hormones, and nutrition.
• Biochemistry and Genetics : Organic compounds in plants, genetic principles, PCR techniques, and tissue culture methods.
• Pharmacognosy and Microbiology : Study of medicinal plants and the structure and function of viruses and bacteria.

Physiology

• Cell and Metabolism : Enzyme functions, energy production mechanisms including ATP synthesis and the TCA cycle.
• Nutrition and Immunity : Components of a balanced diet, immune system responses, and blood group classification.
• Organ Systems : Detailed study of the heart (including ECG interpretation), lungs, kidneys, brain, and nervous system.
• Hormones and Reproduction : Hormonal regulation, menstrual cycle, and methods of birth control.
• Applied Physiology : Effects of environmental factors on the human body and the use of medical diagnostic devices such as ECG and MRI.

Important Notes: Regular practical exercises and diagrammatic representations are essential for mastering this syllabus. Focus on understanding concepts rather than rote memorization. Use past examination papers for practice and time management.
