Golgi Apparatus (also known as Golgi Complex)

• A sack like collection of flattened membranous sacs
• One side of the sack is formed by the fusion of membranes of vesicles from ER (a network of membranes inside the cell) and the other formed from swellings at the margins that become pinched off.
• Present in all cells but especially prominent in metabolically active cells such as secretory cells.
• Produces materials for plant cell walls and insect cuticles
• After processing, material passes out of the cell or enters Lysosomes (small spherical vesicles bound by a single membrane) to be taken to other organelles
