AP BIOLOGY
Cell Organelle Function Explorer
Explore an interactive diagram of a eukaryotic cell. Click on organelles like the Nucleus, Rough/Smooth ER, Golgi, and Mitochondria to view detailed functions.
AP BIOLOGY
Osmosis & Water Potential Calculator
Calculate and visualize water potential (Ψ = Ψs + Ψp) across a plant cell membrane. Watch water movement and cell plasmolysis/turgidity based on hypertonic/hypotonic environments.
AP BIOLOGY
Surface Area to Volume Ratio Animator
Visualize how increasing cell size severely decreases the SA:V ratio, simulating diffusion waves to show why cells must remain small or develop folds.
AP BIOLOGY
Endosymbiotic Theory Visualizer
Step through an animated history of a eukaryotic cell engulfing aerobic and photosynthetic bacteria to form mitochondria and chloroplasts, respectively.
