What you’ll learn5 learning objectivesChoose one objective for a focused lesson, or study the complete topic.3.1.1Diffusion• Describe diffusion as the net movement of particles from a region of their higher concentration to a region of their lower concentration (i.e. down a concentration gradient), as a result of their random movementSyllabus objective3.1.2Energy for diffusion comes• State that the energy for diffusion comes from the kinetic energy of random movement of molecules and ionsSyllabus objective3.1.3Diffusion through cell membranes• State that some substances move into and out of cells by diffusion through the cell membraneSyllabus objective3.1.4Importance of diffusion• Describe the importance of diffusion of gases and solutes in living organismsSyllabus objective3.1.5Factors that influence diffusion• Investigate the factors that influence diffusion, limited to: surface area, temperature, concentration gradient and distanceSyllabus objective
