TEM of endoplasmic reticulum in mammalian cell

Rough endoplasmic reticulum. Transmission Electron Micrograph (TEM) of a section through a mammalian cell revealing rough endoplasmic reticulum (ER). ER is the system of membranes seen running across at upper image. Small granules attached to the membrane of the ER are ribosomes, the sites of protein synthesis. At lower right the large mass of the cell nucleus is seen, with dark areas of chromatin. ER originates from the nuclear membrane & divides the cell cytoplasm into a network of cavities called cisternae. Small vesicles bud from the ER to transport proteins and fats around the cell. Magnification: x66, 000 at 8x10 inch size
