Vesicle transport requires energy, so it is also a form of active transport.
Active transport involves movement of substances against a chemical gradient.
Vesicle transport requires energy for movement of substances against a chemical gradient.
Why does vesicle transport need energy? 
[1] it helps plants in growing
[2] to prevent movement
[3] for movement of substances
[4] during the day
[5] Transfers energy
[6] flow of electrons
[7] to breath
[8] magnetism
