Cell Organelles – summary table Name of organelle(shape and size)StructureFunctionDiagramPlant / animal cellRibosome(20-30nm)The smallest organelle in the cell (visible only with the electron microscope). It is made of ribosomal RNA and protein. Larger and smaller subunits. It is involved in a process called translation in which proteins are formed.                      BothEndoplasmic reticulum (ER)ROUGH It’s a system with of membranes within the cytoplasm, which enclose a space known as the lumen.It has ribosomes on its surface.It is involved in the production of secretory proteins.

                         BothEndoplasmic reticulum (ER)SMOOTHIt’s a system with of membranes within the cytoplasm, which enclose a space known as the lumen.It has no ribosomes on its surface.Detoxification of drugs and lipid synthesis (including phospholipids and steroids) etc.             BothGolgi ApparatusIt’s a series of flattened membranous sacs (cisternae) looking like a stack of Pita bread.It’s dynamic structure as vesicles are constantly being added from the ER, and new vesicles are budding off.Cells may have a few to several hundred of these structures.It receives vesicles full of protein from the ER, then may be modified and packaged into vesicles which may transport them to other ...
