Structures: Golgi bodies consist of a system of membrane-bound vesicles arranged in stacks parallel to each other called cisterns. These membranes have connections with the membrane of endoplasmic reticulum (ER).

Functions:

(1) The material synthesised near the ER is packaged and dispatched to various target inside and outside the cell through Golgi apparatus.

(2) It also stores, modifies and helps in the packaging of products in vesicles.

(3) In some cases, complex sugars may be made from simple sugars in it.

(4) It also helps in the formation of lysosomes.
