About this NEET Biology practice test

NEET Biology counts for 360 of 720 marks, so it is the single biggest scoring vertical for medical aspirants. This practice test follows the official NTA syllabus and is built strictly from the Class 11 and Class 12 NCERT Biology textbooks. Coverage spans Cell Biology, Genetics, Plant and Human Physiology, Reproduction, Evolution, Ecology and Biotechnology. The starter set deliberately mixes fact-based MCQs (where memory matters) with concept-based questions (where understanding matters) so practice mirrors the real NEET Biology section. Each generated question comes with a short explanation that reinforces the underlying NCERT line.

Answer key & quick explanations

Short answers for the sample questions above. Use this to self-check before generating a fresh AI-built mock test.

  1. Cell discovery: Cell is the structural and functional unit of life. Discovered by Robert Hooke (1665).
  2. Kidney functional unit: Nephron.
  3. Independent assortment: Alleles of different genes assort into gametes independently of one another (during meiosis).
  4. Mitosis vs meiosis: Mitosis — 1 division, 2 identical diploid daughter cells (growth/repair). Meiosis — 2 divisions, 4 haploid daughter cells (gamete formation).
  5. Human gametes: Male — sperm. Female — ovum (egg).
  6. Photosynthesis equation: 6CO₂ + 6H₂O → (in presence of light & chlorophyll) C₆H₁₂O₆ + 6O₂.
  7. Pancreas role: Secretes pancreatic juice (amylase, trypsin, lipase) into duodenum and hormones (insulin, glucagon) into blood.
  8. Ecosystem components: Biotic (plants, animals, microbes) and abiotic (water, air, soil, temperature).
  9. Enzyme example: Biological catalysts that speed up reactions; eg. salivary amylase digests starch to maltose.
  10. Heart chambers: Four — right atrium, right ventricle, left atrium, left ventricle.
  11. Chlorophyll function: Pigment that absorbs light energy needed for photosynthesis.
  12. ATP: Adenosine triphosphate — stores and releases energy during cellular reactions; called the energy currency of the cell.
  13. In-situ vs ex-situ: In-situ — protect species in their natural habitat (national parks). Ex-situ — outside habitat (zoos, seed banks).
  14. Lymphatic system: Drains tissue fluid back to blood, transports fats from intestine, and filters pathogens via lymph nodes.
  15. Biotechnology applications: Production of insulin via recombinant DNA, vaccines, gene therapy.
