Rating Newest Oldest. Best Answer: Vesicles come from rough ER and the golgi apparatus. They are made of membrane. There are two different types of vesicles: 1. Take modified materials from golgi or rough ER to other parts of the cell. 2. Take secretory materials (usually proteins) from the golgi apparatus to the cell wall.They release the materials to be secreted from the cell. They then join with the plasma membrane.ating Newest Oldest. Best Answer: Vesicles come from rough ER and the golgi apparatus. They are made of membrane. There are two different types of vesicles: 1.
