Tuition Centre Singapore Biology Tuition – Movement of Substances (Diffusion)   Common Error 1 Diffusion of particles from one region to another takes place at a constant speed. Correct Concept 1 The concentration gradient determines the speed of diffusion. As diffusion proceeds, the concentration gradient decreases. The speed of diffusion thus decreases as well   Common Error 2 During diffusion, particles only move in the direction of the region of lower concentration. Correct Concept 2 Particles move randomly in all directions. The net movement of particles is in the direction of the region of lower concentration   Common Error 3 Each cell is a self-contained unit of life. Correct Concept 3 Cells interact with other cells in a network of communication. There are many ...
