This article describes an organelle, a cell component with its own distinctive structure and function. In eukaryotic cells, this is bounded by its own membrane, which is a lipid bilayer made of phospholipid.

Definition

The Golgi apparatus (also called the Golgi body or Golgi apparatus) is an organelle found in most eukaryotic cells whose function is to package proteins (after their synthesis by the ribosomes) in a form that can be secreted via vesicles.

Summary

Item Value
Type of organisms whose cells contain the Golgi apparatus eukaryotic cells
Type of cells within the organisms that contain the Golgi apparatus Most cells. The red blood cells in mammals (see mammalian red blood cells) are exceptions.
Number per cell 1 (?)
Size ?
Location within cell near the endoplasmic reticulum, and proteins and stuff are transfered from the endoplasmic reticulum to the Golgi body via vesicles.
Structural components The Golgi apparatus is composed of stacks of cisernae. Each stack is called a dictyosome and contains 4-8 cisternae.
Chemical constituents proteins, what else?
Control of the entry and exit of materials ?
