Golgi bodies (Golgi Apparatus) are stacks of flattened ‘sacs’ made of smooth membrane. The Golgi body receives proteins and materials from the endoplasmic reticulum, it then packages them and distributes them. Golgi bodies are involved in the packaging and secretion of proteins and carbohydrates manufactured by the cell. E.g. gland cells such as salivary glands cells, which secrete saliva. As well a packaging the Golgi body also manufactures some carbohydrates for use outside the cell, these are packaged into vesicles that bud off from the Golgi body and migrate to the cell membrane, this secretion is an example of Exocytosis.
