WB ANM GNM Life Science Important Chapters 2025

Here are WB ANM GNM Life Science Important Chapters 2025, which you need to focus on. Each chapter consists of scoring sub-subjects and repeated questions, which will help you maximize your concentration in preparation for marks.

Now that we've learned about the most important chapters in WB ANM GNM Life Science 2025, let's learn how to study each chapter step by step in an easy way with tips and example questions.

Tips to Master Cellular Organization Chapter

• Differentiate between animal and plant cell diagrams. Label all organelles and cytoplasmic inclusions such as the nucleus, mitochondria, and chloroplasts.
• Revise functions of the organelles into simple one-liners (for example, mitochondria: powerhouse; chloroplasts: photosynthesis).
• Know the types of tissues (epithelial, muscular, connective, and nervous) by everyday solutions.
• Practice differentiation (e.g., prokaryotic vs. eukaryotic; plant vs. animal cell).
• Talk about ribosomes, lysosomes, and Golgi bodies with flashcards.

Example Questions for Cellular Organization

Chapter - Fundamental Processes

• Focus on photosynthesis: equation, chlorophyll role, light vs. dark reaction.
• As for respiration, figure out the differences between aerobic respiration and anaerobic respiration, glycolysis, and ATP (the energy currency).
• Understand digestion basics -  Mouth, stomach, and small intestine-Commands of enzymes like amylase and pepsin.
• Learn using flow diagrams (food - energy, glucose - ATP).
• Compare and contrast photosynthesis versus respiration in a simple table.
• Practice the equations (Photosynthesis: 6CO₂ + 6H₂O - C₆H₁₂O₆ + O₂).

Example for Fundamental Processes Chapter

Tips to Master Systems Physiology (Plant & Animal)

• Human dissection physiology - majorly the circulatory, respiratory, digestive, excretory, nervous, and reproductive systems.
• Plant Physiology: transport (xylem/phloem); transpiration and briefly photosynthesis.
• Draw diagrams- heart, nephron, lungs, plant vascular system, label clearly.
• Make mnemonics- e.g. for cranial nerves, blood flow, or plant tissues.
• Revise often- 30-40% of Life Science questions in WB ANM GNM exams are guaranteed to come from this chapter.

Example Questions on Systems Physiology

Inheritance Biology Chapter

• Mendelian Genetics - comprehend inheritance laws - dominant vs. recessive traits, mono- and dihybrid crosses.
• DNA & RNA - structure, function, replication, transcription, and translation.
• Flowcharts and tables - relating to gene expression, Punnett squares, types of inheritance.
• Relate to Examples - pea plants (Mendel), sickle cell anemia, blood groups.
• Revise Terms and definitions - allele, genotype, phenotype, homozygous, heterozygous.

Example Questions on Inheritance

Tips for Ecological Principles

• Basics of the ecosystem: understand producers, consumers, decomposers, and energy flow.
• Food chains and Food webs: draw diagrams, label trophic levels, and energy transfer efficiency.
• Biogeochemical cycles: carbon, nitrogen, and water cycles related to environmental issues.
• Population and community ecology: study population growth and carrying capacity or interactions - predation or competition.
• Current examples of environment: pollution, global warming, conservation programs in India.

Examples

Life Science Chapter on Diversity of Life Forms

• Introduction to Classification-level study-Kingdoms, Phyla, Classes, and the main characteristics of each.
• Plant diversity-Bryophytes, Pteridophytes, Gymnosperms, Angiosperms. Their reproductive structures must be noted.
• Animal diversity-from Porifera to Chordata, with emphasis on symmetry, coelom, and digestive system.
• Use charts & diagrams- one-page classification chart serves as a quick revision.
• Repeated questions-NCERT examples on key differences between groups are commonly asked.

Example Questions

How to learn Cell Signaling & Communication

• Understand basics of signaling – study types of signals: chemical, electrical, hormonal.
• Cell receptors – memorize types (G-protein, ion channel, tyrosine kinase) and their functions.
• Signal transduction pathways – focus on steps like reception, transduction, response; use simple flowcharts.
• Examples in humans – link hormones (insulin, adrenaline) to their effects for easier recall.
• Practice MCQs – most WB ANM GNM questions are direct from definitions and pathways.

Example for Cell Signaling & Communication

Application and Methods in Biology

• Laboratory techniques in microscopy, stain techniques, centrifugation, and electrophoresis.
• Essentials of experimental design: hypothesis, controls, variables, interpretation of data.
• Real-world examples: focus on applications such as PCR, cloning, and even gene editing CRISPR basics in biotechnology. Examples will include agarose gel electrophoresis for DNA separation.
• Practice questions: Most MCQs are relatively direct and example-based and focus on processes and methods.

Examples on Application and Methods in Biology

Follow the simple study tips for each chapter and make plenty of drawings or flowcharts to aid memory. Keep studying these important topics daily till you feel confident about the exam. I know at certain times, it may get overwhelming to study all subjects together. Thus, we have a step-by-step plan for you - do check out our 30-Day Roadmap for WB ANM GNM 2025 Exam Preparation!
