- Golgi apparatus is an organelle found in the eukaryotic cells which forms a complex of vesicles and folded membranes within the cytoplasm.
- Its main function is sorting, modifying and packaging of proteins.
- It is also involved in secretion, glycosylation of proteins and lipids and helps in intracellular transport.
