Understanding concepts like monohybrid and dihybrid crosses, incomplete dominance, and codominance is vital. * **Molecular Basis of Inheritance:** DNA structure and function, replication, transcription, translation, gene expression, and regulation are core concepts. The Human Genome Project and its implications are also important. * **Evolution:** Theories of evolution (Darwinism, Lamarckism), evidence for evolution, adaptive radiation, human evolution, and the mechanisms of evolution (natural selection, genetic drift) are key areas.

2. Human Physiology: Understanding Our Own Biology

This extensive unit covers the intricate workings of the human body and is a consistent source of numerous questions. A deep understanding of each system is required. * **Digestion and Absorption:** The process of digestion, enzymes involved, and nutrient absorption mechanisms. * **Breathing and Respiration:** Respiratory organs, gas exchange, transport of gases, and regulation of respiration. * **Body Fluids and Circulation:** Blood composition, circulation pathways, cardiac cycle, and ECG. * **Excretory Products and Their Elimination:** Nephron structure, urine formation, osmoregulation, and kidney function. * **Locomotion and Movement:** Types of muscles, muscle contraction, and skeletal system. * **Neural Control and Coordination:** Nervous system structure, neuron function, reflex action, and endocrine glands and hormones. * **Chemical Coordination and Integration:** Hormonal regulation of various bodily functions, feedback mechanisms.

3. Plant Physiology: The Green World's Secrets

Understanding how plants function is another significant area tested in NEET. * **Photosynthesis in Higher Plants:** Light and dark reactions, factors affecting photosynthesis, and C3/C4 pathways. * **Respiration in Plants:** Glycolysis, Krebs cycle, electron transport chain, and oxidative phosphorylation. * **Plant Growth and Development:** Plant hormones, photoperiodism, vernalization, and seed dormancy.

4. Reproduction: The Continuity of Life

This unit covers reproductive strategies in various organisms, including humans. * **Reproduction in Organisms:** Asexual and sexual reproduction. * **Sexual Reproduction in Flowering Plants:** Flower structure, pollination, fertilization, and seed/fruit development. * **Human Reproduction:** Male and female reproductive systems, gametogenesis, menstrual cycle, fertilization, implantation, pregnancy, and parturition. * **Reproductive Health:** Contraception, STDs, and infertility.

5. Biotechnology and its Applications: Modern Biological Tools

This is a relatively newer but increasingly important area in NEET. * **Biotechnology: Principles and Processes:** Recombinant DNA technology, PCR, gene cloning, and vectors. * **Biotechnology and its Applications:** Genetically modified organisms (GMOs), Bt cotton, gene therapy, and biopiracy.

6. Ecology: The Interplay of Life

Understanding the interactions between organisms and their environment is crucial. * **Organisms and Populations:** Population attributes, growth models, and interactions. * **Ecosystem:** Structure, function, energy flow, nutrient cycling, and ecological succession. * **Biodiversity and Conservation:** Levels of biodiversity, importance, threats, and conservation strategies. * **Environmental Issues:** Pollution, waste management, and climate change.

Strategic Study Plan for NEET 2026 Biology
