Define in brief about the Golgi bodies

In a cell is achieved in a remarkable fashion by the Golgi bodies. The latter receive the newly synthesised proteins from the rough endoplasmic reticulum, and put identifying marks on them, just as the pin code numbers are put on an address. The Golgi bodies carry out this process by introducing certain specific and different chemical signals in the form of certain carbohydrate residues on the proteins, in a process called glycosylation. Such glycosylated proteins are recognised at different sites within the cell. The Golgi bodies, thus, play a key role in chemically modifying newly synthesised proteins, and sort them out to make them reach their appropriate destinations. Fig. below depicts diagrammatically how the Golgi bodies receive three differen1 proteins made in the endoplasmic reticulum, and sort them out and process them to become part of the lysosomal enzymes or be secreted out of the cell or become a part of the plasma membranes.
