1.This very broad definition includes many different types of cytoplamsic structures that have specific names and functions and are not usually refered to as vesicles but as organelles. For example:

• endoplasmic reticulum

• golgi apparatus

• choroplasts

• mitochondria

• lysosomes

2. There are other kinds of intracellular structures that are usually refered to as vesicels. For example

• transport vesicles

• endocytotic vesicles

• exocytotic vesicles

• acrosomal vesicle

• secondary lysosomal vesicle

• compartment for the uncoupling of receptor and ligand (CURL)

• secretory vesicle

• adipose vesicles

Vacuoles

Plants and some animals often have very large vesicles that are involved in osmoregulation. These are often called vacuoles. For example
