🔬 TOP Biology Points for NEET Preparation (Must-Know Concepts) 🧬 Class 11: Diversity of Living Organisms to Plant Physiology 1. Binomial Nomenclature: Genus + species format, e.g., Homo sapiens. 2. Five Kingdom Classification: Based on cell structure, mode of nutrition, body organization. 3. Viruses lack cellular structure but have genetic material (DNA/RNA). 4. Lichen = Symbiosis of Algae (food) + Fungi (shelter). 5. Monera (Bacteria) are prokaryotic; only kingdom with peptidoglycan in cell wall. 6. Gymnosperms have naked seeds; angiosperms have covered seeds. 7. Xylem = water transport; Phloem = food transport. 8. C4 pathway plants (e.g., maize) are more efficient in hot climates than C3 plants. 9. CAM plants (e.g., cactus) open stomata at night to prevent water loss. 10. Photosystem I and II are involved in the light reaction of photosynthesis. 🧠 Class 11: Human Physiology 11. Saliva contains amylase, starts digestion of starch. 12. Pepsin in stomach requires acidic pH (~1.5 to 2). 13. Bile has no enzymes but emulsifies fat to aid digestion. 14. Nephron is functional unit of kidney; filtration occurs in Bowman’s capsule. 15. Insulin lowers blood sugar; glucagon increases it (both from pancreas). 16. SA Node = Pacemaker of heart; initiates heartbeat. 17. Oxygen transport: 98.5% by hemoglobin, rest dissolved in plasma. 18. Synapse = Junction between two neurons, uses neurotransmitters. 19. Hormones are secreted directly into the blood (ductless glands). 20. Reflex arc involves sensory neuron → spinal cord → motor neuron. --- 🌱 Class 12: Reproduction to Ecology 21. Pollen grain is male gametophyte, ovule is female gametophyte. 22.
