passive transport  Active transport necessitates energy to move substances against their concentration gradient, whereas passive transport requires no cellular Active transport helps in the uphill movement of substances On the other hand, passive transport helps in the downward movement of substances

Transport Without Energy Expenditure By The Cell Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell  While active transport requires energy and work, passive transport does not There are several different types of this easy movement of molecules It could be
