Diagram of a typical animal cell (eukaryote). Organelles:(1) nucleolus (2) nucleus (3) ribosome (4) vesicle (5) rough endoplasmic reticulum (ER) (6) golgi apparatus (7) cytoskeleton (8) smooth ER (9) mitochondria (10) vacuole (11) cytoplasm (12) lysosome (13) centrioles
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]
