§1.0 µm in diameter
§Takes materials from the Endoplasmic Reticulum
§Readies products for export from the cell
§These products are then transferred
to other organelles or out of the cell
Want me an example?
Have you ever made a sandwich for lunch and sealed it inside a plastic bag? That's what happens inside the Golgi complex. Important materials that the cell needs to grow and repair itself are packaged in the membrane material made inside the Golgi complex and then shipped to the parts of the cell where they are needed.
The Golgi Complex (or Golgi Apparatus, or Golgi Body) is a cytoplasmic structure composed of multiple cisternae (pools of solution surrounded by membranes) arranged to look like a stack of pancakes hovering over the Endoplasmic Reticulum (ER). The Golgi Complex can be subdivided into three principal parts - cis, medial, and trans - based on proximity to the ER. The cis- and trans- Golgi stacks look discontinuous and irregular as vesicles are constantly joining and leaving, so they are usually referred to as the cis Golgi network (CGN) and trans Golgi network (TGN), respectively. The medial Golgi can have any number of cisternae, which are referred to collectively as the medial stacks. The function of the Golgi Complex is to...
