Rough endoplasmic reticulum,coloured transmission electron micrograph (TEM). Endoplasmic reticulum (ER) is a membranous cell organelle responsible for functions such as protein production,transportation and storage. The membranes enclose an internal cellular space known as the ER lumen. Rough ER has ribosomes (small dots) attached,while smooth ER,a site of lipid synthesis,lacks ribosomes. Part of the cell nucleus is at lower right,and part of a mitochondrion is at lower left. Magnification: x28,600 when printed at 10 centimetres across | |
