Question
Write short note on the following:
Golgi apparatus
Advertisements
Solution
- Golgi apparatus consists of a set of membrane-bounded, fluid-filled vesicles, vacuoles, and flattened cisternae.
- Cisternae are stacked together in parallel rows. They are formed at one end of the stack, called cis face of Golgi, and are budded off as vesicles at the other face, called trans face of Golgi.
- Golgi apparatus arises from the membrane of smooth endoplasmic reticulum.
- Golgi saccules (cisternae at cis and trans face) are constantly renewed. Distal saccules (trans face) disappear after vesicle formation.
- The main function of Golgi apparatus is to secrete vacuoles or secretory vesicles that contain cellular secretions such as enzymes, proteins, and cellulose.
