Mammalian cell. Coloured Transmission Electron Micrograph (TEM) of a section through a mammalian cell. At top right is part of the nucleus (large sphere) containing genetic material in the form of DNA. A mitochondrion is seen (oval-shaped, blue) at upper left in the cell cytoplasm. Mitochrondria are sites of cell respiration, the chemical process which uses oxygen to oxidise sugars and fats to produce energy. At lower frame are elongated membranes of the rough endoplasmic reticulum (ER). The ER forms channels for storage and transport of cell substances. Rough ER is coated in ribosomes (dots) which make proteins.
