- Single membrane-bound
- Consists of flattened membranous stacks of cisternae
- - seen as a single large stack in animal cells; separate stacks in plant cells
At cis face
(outer convex face), new cisternae are constantly formed
by fusion of vesicles from rough and smooth ER.
At trans face
(inner concave face), Golgi vesicles bud off from the Golgi apparatus to form vesicles
such as lysosomes, and secretory vesicles which contain products destined for secretion out of the cell.
- 1) Synthesis of certain macromolecules (e.g. pectin found in cell wall of plant cells)
- 2) Formation of cell plate in plant cells at final stage of cell division - Golgi-derived vesicles containing pectin and hemicelluloses move to middle of cell where they fuse to form the cell plate.
- 3) Formation of lysosomes in some animal cells involved in phagocytosis
- 4) Receives products (proteins and lipids) from ER and chemically modifies them
- - At trans face, modified proteins are sorted, packaged and transported to various cellular destinations
- 5) Replenishment of cell surface membrane
