IGCSE Biology Simulations

Master IGCSE Biology concepts through interactive hands-on simulations. Explore diffusion, enzyme kinetics, circulation, genetics, osmosis, and photosynthesis with real-time visualisations.

Biology is the study of life at every level, from molecular processes within cells to the interactions of organisms in ecosystems. Our interactive Biology simulations provide a virtual laboratory where you can visualise cellular processes, manipulate conditions, and observe the results in real time.

Each simulation is designed to complement your revision, allowing you to explore transport mechanisms, enzyme behaviour, cardiovascular function, inheritance patterns, and photosynthesis with immediate visual feedback and interactive controls.
