| Here are few examples of images and animation clips taken from 'the Cell'. The main module contains 12 3D graphics describing the cell components such as the nucleus, cell membrane etc. Several Scanning Electron Microscope images show among others red blood cell and bone cell. Animation clips demonstrate the cell division process, Duplication of DNA and other processes. |

The red blood cells are biconcave disks of 8 µ
diameter and 1 - 2 micron in thickness. Because of the great excess of the cell membrane
RBC can deform easily when moving through thin capillaries. RBC constitute 40% of the blood by volume and the average number of RBC in one cubic millimeter of blood is 5 million. |

Osteoblasts are responsible for synthesis, deposition and mineralization of the bone matrix. Osteoblast secrete type I collagen the main component of the organic bone matrix. Mineralization is affected by the deposition of tiny crystals of calcium phosphate. Osteoblasts are 15-30 micron across. They are found mainly at the surfaces of a mature bone were they form a monolayer.

The basic functional components of the cell are called organelles and include: nucleus(N), endoplasmic reticulum(ER), two centrioles(C), golgi complex(G), several mitochondrias(M), microtubules(F), microfilaments(F) and the cell's membrane(Me). |
|
Nuclear membrane consist of an inner and outer membrane with a perinuclear space between them. The outer membrane is occasionally continuous with the endoplasmic reticulum and is studded with ribosomes at the 'outside' surface.
