Biology SL

Chapter Simulation Registry

The IB Biology SL path, projected from the shared textbook without HL-only topics or extensions.

Chapter 1: Elements, Molecules and Water

Begin molecular biology with the elements shared by living systems, the dose-dependent roles of trace elements, and the molecular explanation for water's life-supporting properties.

Chapter 2: Metabolism, Respiration and Photosynthesis

Follow energy and matter through enzyme-controlled pathways, ATP production in respiration, and carbon fixation in photosynthesis—from active-site collisions to chemiosmotic membranes.

2 simulation entries

Open chapter simulations

Chapter 3: DNA and Protein Synthesis

Follow genetic information from faithful DNA copying through transcription, RNA processing and translation, then investigate mutation, gene editing and epigenetic control.

Chapter 4: Genetics

Connect chromosome organization to inheritance, predict simple and complex crosses, infer family genotypes, and test linkage models with recombination and chi-squared evidence.

1 simulation entries

Open chapter simulations

Chapter 5: Cell Structure

Build cell biology from origin-of-life evidence through prokaryotic and eukaryotic organization, endosymbiosis, microscopy, viruses and rapid viral evolution.

Chapter 6: Cell Function

Explain how membranes control exchange, organelles coordinate cellular work, geometry constrains size, and cell division preserves or reshuffles genetic information.

Chapter 7: Cell Control and Communication

Explain how cells detect, transmit and integrate information through receptors, neurons, synapses, hormones, feedback systems and plant growth regulators.

Chapter 8: Physiology

Build a connected account of multicellular organization, animal and plant transport, gas exchange, reproduction and homeostasis through structure, gradients and feedback.

Chapter 9: Coordination, Muscles and Motility

Connect nervous coordination to reflexes, enteric movement, skeletons and joints, sliding-filament contraction, motor-unit recruitment and whole-animal locomotion.

Chapter 10: Defence against Disease

Build disease defence from skin and clotting through innate and adaptive immunity, then connect HIV, antibiotics, zoonoses, allergy and vaccination to population health.

Chapter 11: Evolution, Speciation and Ecosystems

Reconstruct ancestry with classification and cladistics, model how gene pools evolve and split, and connect adaptation, niches and competition to biodiversity.

1 simulation entries

Open chapter simulations

Chapter 12: Ecological Relationships

Trace nutrition, energy, matter and population change through ecosystems, then evaluate succession, biodiversity loss, conservation and climate-driven disruption.
