Energy is required for substances to pass into or out of the cell in Active Transportation, while in Passive transportation energy is not required.
Transportation within Cell
The Transportation in Cell is the work of Plasma Membrane. A Plasma Membrane controls everything that pass into or out of the cell. This transportation can be divided into two parts: Active and Passive Transportation.
For Active transportation there is the use of Energy because substance in lower concentration needs energy to transport into higher concentration.
For Passive transportation there is no need of energy, for example osmosis.
