How do substances travel in the cell?

Passive transport: diffusion. Some substances pass through small holes in the surface cell membrane. ... the higher the concentration difference, the faster the rate of diffusion. small particles (ions or molecules) diffuse more quickly than large ones.

Hey mate here is your answer
The efficiency of movement of substances in and out of a cell is determined by its volume to surface area ratio. Selected substances can move up a concentration gradient with the help of specialized molecules embedded in the membrane. This is called assisted diffusion or active transport.
Hope this answer will help you!!!
