Cell organelles. False-colour transmission electron micrograph of rough endoplasmic reticulum (parallel yellow structures) in a tissue culture cell. The endoplasmic reticulum is a complicated system of membranes which forms a network of flattened cavities,or cisternae,throughout the cytoplasm. These function as reservoirs and channels for the storage and transport of proteins and lipids. Rough endoplasmic reticulum is coated in tiny protein-synthesising particles known as ribosomes and is,in general,responsible for the synthesis of proteins secreted by the cell. The large red bodies are lysosomes. Magnification: x13,000 at 6x4.5cm size | |
