📚 Chapter Breakdown & Syllabus Scope
Total 5 ChaptersCell & Its Structure
কোষ ও এর গঠন
Cell wall, fluid mosaic model, organelles (mitochondria, chloroplasts), DNA double helix, and replication.
Explains biological limits on cell size: as radius r grows, SA/V ratio drops by 3/r.
Genetics & Evolution
জিনতত্ত্ব ও বিবর্তন
Mendelian genetics & exceptions, sex determination, sex-linked disorders (hemophilia, color blindness), and evolution.
Calculates allele (p, q) and genotype frequencies (p^2, 2pq, q^2) in non-evolving populations.
Modified dihybrid phenotypic cross ratios caused by gene interaction and epistasis.
Plant Physiology
উদ্ভিদ শরীরতত্ত্ব
Mineral absorption, transpiration, photosynthesis, Calvin & Hatch-Slack cycle, respiration, and RQ.
Ratio of volume of CO2 released to volume of O2 absorbed in cellular respiration.
Number of oxygen molecules evolved per photon absorbed in photosynthetic photochemical reactions.
Human Physiology: Circulation
মানব শরীরতত্ত্ব: রক্ত ও সংবহন
Blood composition, coagulation cascade, cardiac cycle, cardiac output, ECG, and blood pressure.
Total volume of blood pumped by the ventricles per minute as product of Stroke Volume and Heart Rate.
Human Physiology: Excretion & Osmoregulation
মানব শরীরতত্ত্ব: বর্জ্য ও নিষ্কাশন
Kidney morphology, nephron ultrafiltration, GFR, countercurrent mechanism, and osmoregulation.
Volume of ultrafiltrate formed each minute by kidney glomeruli and filtration fraction of renal plasma.
💡 Biology Examination Mastery Strategy
• Always state given parameters and target variables clearly at the top of numerical solutions.
• Display base governing equations before substituting numbers, and maintain explicit unit tracking.
• Box the final answer with its correct SI unit and appropriate significant figures.
• Master Casio fx-991 series shortcut modes (EQN, VECT, BASE-N) for instant verification in timed exams.
• Memorize fundamental physical constants and dimensional unit conversions.
• Use our Biggan.me interactive simulators to explore edge cases and visualize abstract phenomena.
