Tamil Nadu HSE Second Year Biology study plan

Map the full Genetics and Evolution syllabus into a one-page concept tree linking Mendelian inheritance, molecular basis of inheritance, and evolution.

Solve 30 monohybrid and dihybrid cross problems, writing genotype and phenotype ratios without referring to notes.

Explain the lac operon and DNA replication fork enzymes aloud from memory in under five minutes each.

Draw and label the human male and female reproductive systems, then annotate the hormonal control of the menstrual cycle.

Define the stages of oogenesis and spermatogenesis and compare them in a table of at least six differences.

Summarise the experiments establishing DNA as genetic material (Griffith, Avery-MacLeod-McCarty, Hershey-Chase) in cause-effect flow charts.

Describe transcription, translation, and the genetic code, then state at least five features of the code with examples.

Explain sexual reproduction in flowering plants: microsporogenesis, megasporogenesis, double fertilisation, and embryo sac development.

List and define asexual reproductive structures in plants and animals (runners, bulbs, buds, fragmentation, budding, regeneration).

Outline evidence for evolution: fossils, homology, analogy, and biogeography, with one Indian or local example per category.

Classify human diseases into infectious and non-infectious categories, naming pathogen, vector, and one control measure for each major disease.

Describe immunity types, vaccines, and the biology of HIV and AIDS progression.

Explain the use of microbes in household and industrial products, sewage treatment, biogas, and biocontrol.

Outline plant breeding steps, hybridisation types, and green revolution contributions relevant to Tamil Nadu crops.

Build a taxonomic key distinguishing major plant and animal phyla using defining features only.

Describe the tools of genetic engineering: restriction enzymes, vectors, host systems, and selectable markers.

Explain recombinant DNA technology steps from gene isolation to clone selection.

Summarise biotechnological applications in agriculture (Bt crops, RNA interference) and medicine (insulin, gene therapy).

Evaluate biosafety, biopiracy, and patent issues with reasoned arguments.

Revise weeks 1-3 weak areas identified from self-test error logs.

Define population attributes (density, growth models, life tables) and solve logistic and exponential growth problems.

Describe ecosystem structure, energy flow, ecological pyramids, and nutrient cycling with labelled diagrams.

Explain biodiversity patterns, hotspots, and in-situ versus ex-situ conservation strategies.

Analyse environmental issues: pollution types, greenhouse effect, ozone depletion, and solid waste management.

Draw and label the carbon and phosphorus cycles from memory.

Sequence the phases of the cell cycle and describe mitotic and meiotic events with checkpoint control points.

Classify biomolecules and explain enzyme kinetics including competitive and non-competitive inhibition.

Compare prokaryotic and eukaryotic organelles and describe membrane transport mechanisms.

Trace the light and dark reactions of photosynthesis with the Z-scheme and Calvin cycle products.

Outline glycolysis, Krebs cycle, and oxidative phosphorylation with ATP yields per glucose.

Explain water and mineral transport: root pressure, transpiration pull, cohesion-tension, and phloem loading.

List essential mineral elements, their deficiency symptoms, and the role of nitrogen fixation.

Describe plant growth regulators and photoperiodism with one experimental example each.

Distinguish aerobic and anaerobic respiration in plants including the RQ concept.

Revisit cell biology numericals and diagram-based questions from week 6.

Take two full-length timed mock papers under exam conditions and score them strictly.

Re-teach the five weakest sub-topics from all error logs using blank-paper recall.

Memorise high-yield diagrams and definitions flagged in earlier weeks.

Practice previous-year-style short-answer and long-answer formats for time management.
