So diffusion is a form of passive transport, right, so the particles are moving with the concentration gradient from a region higher density to a region of lower density. This happens naturally as an effect of molecules colliding, so they do not require the cell to make an effort and use up energy. Active transport requires the cell to use energy, because in active transport the particles are moving from a region of lower density to one of higher density, against the concentration gradient, this is not natural so the cell needs to make an effort and use energy if it wants the particles to pass through its membrane.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
