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: -A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

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: -Foundation of Vesicles The Golgi apparatus gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell.

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.
