Photosynthesis: definition, overall balanced equation and significance for life
Chloroplast structure as the site of light and dark reactions; stomata opening and closing
Light (photochemical) phase: activation of chlorophyll, photolysis of water, release of oxygen, ATP and NADPH formation
Dark (biosynthetic) phase: combination of hydrogen from NADPH with CO2 to form glucose
Adaptations of leaves for photosynthesis
Experiments: destarching, starch test, necessity of light, CO2 and chlorophyll; release of oxygen by hydrilla
The carbon cycle
