is a type of bulk transport in which a vesicle fuses with the cell's plasma membrane to release its contents outside the cell.

The process you're referring to is called Exocytosis. Here are the steps:

1. The substance to be exported is first packaged into a vesicle inside the cell. This can happen in several ways, depending on the substance. For example, proteins are synthesized in the rough endoplasmic reticulum and then transported to the Golgi apparatus, where they are packaged into vesicles.

2. The vesicle, containing the substance to be exported, moves through the cytoplasm towards the plasma membrane. This movement is facilitated by the cytoskeleton, a network of protein fibers that provides structure and shape to the cell.

3. When the vesicle reaches the plasma membrane, it fuses with it. This process is
