HYPERGEEK SUITE

4D Cell Explorer

Turn a living animal cell in 3D, then press play and watch it divide through time: the fourth dimension. Drag it, or use the arrow keys, then pick an organelle to see what it does.

← HyperGeekU

A see-through animal cell with a purple nucleus, orange mitochondria, a teal folded endoplasmic reticulum, green Golgi plates, red lysosomes and tiny ribosome dots. Time: Interphase. The nucleus is whole, with its envelope and faint, loose threads of chromatin inside.

Time: the cell cycle

Interphase (1 of 6): The cell is busy growing and copying its DNA to get ready to divide.

Organelles

Tap an organelle on the cell, or pick one above, to read about it.
