What are carrier vesicles?

Bulk transport:

1. Bulk transport is a type of transport where large quantities of materials and food particles are transported across the membrane.
2. It is achieved with the help of carrier vesicles.
3. The living organisms take their food in bulk in the form of large-sized molecules which cannot cross the plasma membrane.

Final answer:

Carrier vesicles are the vesicles that help to achieve bulk transport across the membrane.
