Net movement of molecules 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.
1 of 9
Osmosis
Diffusion of water molecules from a region of their higher concentration (dilute solution) to a region of their lower concentration (concentrated solution), through a partially permeable membrane.
2 of 9
Enzymes
Proteins that function as biological catalysts.
3 of 9
Photosynthesis
Fundamental process by which plants manufacture carbohydrates from raw materials using energy from light.
4 of 9
Balanced Equation for Photosynthesis
6CO2 + 6H2O -> C6H12O6 + 6O2

Ingestion
Taking substances (e.g. food, drink) into the body through the mouth.
6 of 9
Egestion
Passing out of food that has not been digested, as faeces, through the anus.
7 of 9
Digestion
Breakdown of large, insoluble food molecules into small, water- soluble molecules using mechanical and chemical processes.
