PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Animal cell. Computer artwork of an expanded animal cell. At centre left is the nucleus (purple sphere), which contains the cell's genetic information in the form of DNA (deoxyribonucleic acid, purple stings). Surrounding the nucleus is endoplasmic reticulum (ER, green), a membrane bound organelle that is the site of lipid synthesis and the production of membrane-bound proteins. Also seen are Golgi bodies (orange), a membrane-bound organelle that modifies and packages proteins, and mitochondria (transparent, one at upper centre), which produce the cell's energy.
