The process where a cell uses vesicles to move molecules out is called exocytosis.

Here's how it works:

1. Packaging: The molecules to be transported are packaged into small, membrane-bound sacs called vesicles inside the cell.

2. Transport: The vesicles travel through the cytoplasm, often guided by motor proteins along cytoskeletal tracks.

3. Fusion: The vesicle reaches the cell membrane and fuses with it, releasing its contents outside the cell.

Exocytosis is essential for many cellular functions, including:

* Secretion of hormones, neurotransmitters, and other signaling molecules.

* Removal of cellular waste products.

* Building and maintaining the cell membrane.
