Active transport is a method of cell transport that requires energy. Energy is expended because the cell has to move materials from an area of low concentration to an area of high concentration. Imagine you have 5 large marshmallows in your mouth.
The basic difference between both kinds of transport is that Active Transport requires chemical energy to complete its biochemical transport as it have to move the molecules from lower concentration towards the high concentration which is against the natural law of transportation and it thus requires energy for this purpose, Whereas passive transport is the transport system which does not require any energy or external force as it is a moment of biochemical from higher concentration towards ...
