Answer
FALSE
Explanation
The principle of diffusion explains the process wherein materials (commonly like gases or solutes) move from an area of a higher concentration to an area of lower concentration, essentially, they move along, not against the concentration gradient. Therefore, in the context of cells, during diffusion, substances travel into the cell from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell), thus not against, but along with the concentration gradient.
