The Animal Cell Structure Model is an anatomy model from 3B Scientific and manufactured in Germany. The two piece animal cell model shows the form and structure of a typical animal cell as viewed by an electron microscope. For purposes of better illustration, all important organelles are shown in raised relief and displayed in color, e.g.: * Nucleus * Mitochondrion * Smooth Endoplasmic Reticulum (ER) * Rough Endoplasmic Reticulum (ER) * Basal membrane * Collagen fibers * Golgi apparatus * Microvilli * Lysosome. The model is best used for anatomy studies. The Animal Cell Structure Model is 8.3 x 4.3 x 12.2 in. and weighs 1.76 lbs.
