Animal cell: cutaway illustration showing major ultrastructures and organelles (cell membrane, nucleus, nucleolus, nuclear envelope, nuclear pore, centrioles, microtubule, smooth endoplasmic reticulum (SER), rough endoplasmic reticulum (RER), ribosomes, polysomes, lysosomes, peroxisomes, mitochondria, and Golgi apparatus). Delimited by a plasma membrane (bi-lipid cell membrane). A centrally placed nucleus houses the genetic material (DNA). Jewel like colours and very fine detail make this image ideal to illustrate complexity at the cellular level. Available as a poster from BioCam.com. This image features as a full page colour plate in Richard Dawkins' latest best seller "The Greatest Show on Earth".
