Cell envelope and organelles · Biology
Animal cell explorer
Interactive 3DPeek inside an animal cell — pick an organelle to highlight it and learn its job.
Controls
Drag the sliders or type a value — the simulation updates live.
Study notes
Example: Put a plant cell in pure water. Water rushes in by osmosis, but the cell does not burst — the rigid cellulose wall pushes back (wall pressure), balancing the entry. An animal cell in the same water would swell and burst because it has no wall.
