Found mostly in glandular cells, secretory cells (like pancreatic cells) and liver cells.
It is also found in plant cells, especially younger cells.
It is randomly distributed in cytoplasm of eukaryotic cells.
Golgi Bodies
Structure:
Golgi bodies is a stack of flattened sacs.
This organelle is bounded by a membrane.
Vesicles (small sacs) are always forming on the outside surface of the Golgi bodies.
The content of Golgi bodies include carbohydrates, proteins, lipids, lipoprotein, glycoprotein, glycolipid, steroids, enzymes, cholesterol and others.
Functions:
Stores and processes proteins, lipids, and carbohydrates.
Helps in the secretion of cell products.
Golgi bodies serve as an intracellular transport. Golgi bodies collects, packages, and distributes synthesized substances from one part of the cell to another.
Formation of lysosomes. Hydrolytic enzymes synthesized by ribosomes of RER are transported to Golgi bodies to be packaged into lysosomes.
Protect and extend plasma membrane. Secretory vesicles from Golgi bodies fuse with the plasma membrane and extends the membrane.
