1) The processes of diffusion is used to -differentiate the jobs among cell organelles
-break down molecules to release energy
-produce proteins for the cell to help move molecules against a concentration gradient
-move molecules into or out of cells across the membrane

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
