endoplasmic reticulum

A membrane network within the cytoplasm of cells involved in the synthesis, modification, and transport of cellular materials.

endoplasmic reticulum

(Biology) an extensive intracellular membrane system whose functions include synthesis and transport of lipids and, in regions where ribosomes are attached, of proteins

endoplas′mic retic′ulum

a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum), involved in the transport of materials..

en·do·plas·mic reticulum

A network of membranes within the cytoplasm of many cells that is important in protein synthesis and involved in the transport of cellular materials. All organisms except bacteria have at least one endoplasmic reticulum in their cells. See more at cell.
