Biology (Botany + Zoology) for NEET UG

90 questions — half the paper and the surest route to a rank.

📊 90 Q · 360 marks (50% of the paper)

How toppers play this section

Biology is half of NEET and the most scoring: it is overwhelmingly NCERT recall, diagrams and one-line facts, with little calculation. Human Physiology, Genetics & Molecular Biology, Ecology, Cell Biology and Reproduction are the biggest blocks. The winning method is to read NCERT line by line — including examples, tables and figure captions — because NEET quotes it almost verbatim.

Chapters

Built to the NEET UG blueprint — notes, shortcuts, solved PYQ-style examples and practice in every chapter.

1How NEET Biology WorksBiology is half of NEET — 90 questions, 360 marks — and the surest route to a medical rank because it is overwhelmingly NCERT recall, not calculation. This chapter maps the section, fixes the line-by-line NCERT method that banks these marks, and shows how to read diagrams, tables and captions the way NEET quotes them.⏱ 14 min read

2Cell Biology and BiomoleculesA complete NEET treatment of the cell and the molecules of life — the cell theory, the prokaryote–eukaryote divide, the fluid-mosaic membrane, and every organelle with its structure and function; the biomolecules (carbohydrates, proteins, lipids, nucleic acids) and enzyme action; and the cell cycle with mitosis and meiosis phase by phase. Organised for the line-by-line recall NEET rewards, with the comparisons and exceptions the exam repeats.⏱ 42 min read

3Plant Diversity and MorphologyA complete NEET treatment of biological classification and plant form — the five kingdoms, Monera, Protista and the fungal classes, viruses and lichens; the plant kingdom from algae through bryophytes, pteridophytes and gymnosperms to angiosperms with their alternation of generations; and the morphology of flowering plants — root, stem, leaf, inflorescence, flower, fruit and seed, with floral formulae and the key families. Built for the classification recall NEET rewards.⏱ 40 min read

4Plant Anatomy and PhysiologyA complete NEET treatment of how plants are built and how they work — the meristematic and permanent tissues and tissue systems; water and mineral transport, transpiration and the cohesion–tension theory, and phloem translocation; photosynthesis in full (light reactions, the Calvin cycle, C₄ and photorespiration); cellular respiration (glycolysis, Krebs cycle, electron transport and ATP yield); and plant growth regulators with photoperiodism. Every pathway and mechanism is laid out step by step.⏱ 46 min read

5Animal Diversity and Structural OrganisationA complete NEET treatment of the animal kingdom — the criteria of classification (levels of organisation, symmetry, germ layers, coelom, segmentation and the notochord), every major phylum from Porifera to Chordata with defining features and examples, and the vertebrate classes; then the four animal tissues — epithelial, connective, muscular and nervous. Organised for the classification recall NEET rewards, with the distinguishing features the exam repeats.⏱ 40 min read

6Human Physiology I — Digestion, Respiration and CirculationA complete NEET treatment of three core human systems — digestion (the alimentary canal, the enzymes that break down carbohydrates, proteins and fats, and absorption), respiration (breathing mechanics, respiratory volumes, gas exchange and the transport of O₂ and CO₂), and circulation (blood and blood groups, the four-chambered heart, the cardiac cycle, double circulation and blood pressure). Every enzyme, volume and value the exam repeats is laid out.⏱ 46 min read

7Human Physiology II — Excretion and LocomotionA complete NEET treatment of two more human systems — excretion (the nephron, urine formation by filtration, reabsorption and secretion, the counter-current mechanism, and hormonal regulation by ADH, aldosterone and ANF) and locomotion (skeletal and smooth and cardiac muscle, the sliding-filament mechanism of contraction, the axial and appendicular skeleton, joints, and the common disorders). Every structure, hormone and step the exam repeats is laid out.⏱ 42 min read

8Neural and Chemical CoordinationA complete NEET treatment of the body's two control systems — neural coordination (the neuron, the resting and action potential, the synapse and neurotransmitters, the central and peripheral nervous systems and the reflex arc) and chemical coordination (the endocrine glands from hypothalamus and pituitary to thyroid, adrenal, pancreas and gonads, their hormones and the disorders of excess and deficiency). Every gland, hormone and value the exam repeats is laid out.⏱ 42 min read

9Reproduction in Plants and HumansA complete NEET treatment of reproduction — sexual reproduction in flowering plants (the flower, micro- and megasporogenesis, pollination, double fertilisation, and seed and fruit formation) and human reproduction (the male and female reproductive systems, spermatogenesis and oogenesis, the menstrual cycle, fertilisation, pregnancy and the hormones that run it). Every structure, event and value the exam repeats is laid out.⏱ 46 min read

10Genetics and Molecular InheritanceA complete NEET treatment of heredity — Mendel's laws and the monohybrid and dihybrid ratios, the exceptions of incomplete dominance, codominance, multiple alleles and pleiotropy, the chromosomal theory and sex determination, linkage and human genetic disorders, then the molecular basis of inheritance — DNA as the genetic material, its structure and packaging, replication, transcription, the genetic code, translation and the lac operon. Every ratio, rule and value the exam repeats is laid out.⏱ 50 min read
