• Cell Organelles and Their Functions

  Click any organelle on a labeled cell to see its one-line job, then flip to a name-that-job quiz that scores you. Covers the nucleus, mitochondria, ER, Golgi, ribosomes, and the plant-only parts.

• Interactive Animal Cell

  Click or tab through a labeled animal cell to explore the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, ribosomes, lysosome, vacuole, and more, each with its job explained.

• Interactive Plant Cell (Plant vs Animal Cell)

  Toggle one cell between plant and animal to watch the cell wall, chloroplasts, and large central vacuole appear while the shared parts stay. Includes a turgor slider and a live plant-vs-animal Venn.

• Osmosis vs Diffusion (Interactive Cell Transport)

  A live membrane splits a beaker of water and solute particles. Watch osmosis pull water to the saltier side, diffusion spread solute out, tonicity swell or shrink a cell, and a pump spend ATP.
