GOLGI APPARATUS
Golgi complex was discovered and first described under the name - internal reticular apparatus by Camello Golgi. Alternative names of Golgi complex are - Golgi bodies, Golgi apparatus, Golgisome, Lipochondria, Dalton complex, Idiosome, Baker’s body, etc.
Units of Golgi complex are called - Dictyosomes.
They are composed of
- Cisternae : They are flattened, plate like tubules.
- Vesicles : Are the spherical tubules.
- Vacuoles : Are the large spherical peripherally occurring vesicles.
They are composed of lipids and fats mainly and are also known as Lipochondria.
FUNCTIONS
The main function of Golgi complex - Secretion (enzymes).Golgi complex is abundant in glandular cells.It is mainly concerned with the formation and packing of material fore export from the cell across the plasma membrane by a process of reverse pinocytosis.They form the plasma membrane of the cell.Anterior part of sperms i.e., Acrosome is formed by them.They are responsible for the development and growth of the reproductive cells in mammals. They help in the formation of cell wall.
