3.3) Active transport Active transport: is the movement of particles through a cell membrane from a region of lower concentration to a region of higher concentration using the energy from respiration. Examples of active transport include: uptake of...
3.1) Diffusion Diffusion: is the net movement of molecules and ions from a region of their higher concentration to a region of their lower concentration down a concentration gradient, as a result of their random movement. Diffusion always takes place down a...
3.2) Osmosis Osmosis: is the net movement of water molecules from a region of higher water potential (a dilute solution) to a region of lower water potential (a concentration solution) through a partially permeable membrane. A dilute solution means it...
