In cell biology, a vesicle is a small bubble within a cell, and thus a type of cellular organelle.

Types of vesicles

Vacuoles

Main article: Vacuole

In some mature plant cells, the central vacuole may constitute more than 90% of the cell volume.[1]

Lysosomes

Main article: Lysosome

Transport vesicles

Secretory vesicles

Secretory vesicles store secreted proteins and fuse with the plasma membrane to release their contents.[2]
