Detailed explanation-1: -Proteins are sorted into the regulated secretory pathway in the trans Golgi network, where they are packaged into specialized secretory vesicles. These secretory vesicles, which are larger than other transport vesicles, store their contents until specific signals direct their fusion with the plasma membrane.

Detailed explanation-2: -The organelle that packages proteins before they leave the cell is the Golgi apparatus. The Golgi apparatus will receive proteins from the endoplasmic reticulum via its cis face, and then package them and modify them in various ways.

Detailed explanation-3: -While many types of cells contain only one or several Golgi apparatus, plant cells can contain hundreds. Secretory proteins and glycoproteins, cell membrane proteins, lysosomal proteins, and some glycolipids all pass through the Golgi apparatus at some point in their maturation.

Detailed explanation-4: -The Golgi bodies are regarded as the cell’s post office. It packs protein molecules in the cell and sends them to their destination. It assists in the processing and packaging of lipids and proteins produced by the cell. It causes vesicles to be transported to their final destination.

Detailed explanation-5: -These Golgi stacks contain anywhere from 3 to 20 flattened membrane sacs, which are called cisternae. These Golgi cisternae are usually classified based on what they import and export into the Golgi body, and each contains a different set of processing enzymes.
