carbon dioxide + water ---light energy and chlorophyl---------------->glucose +oxygen
6Co2 + 6H20 ---light energy and chlorohyl---> C6H1206 + 6O2
-Glucose is soluble. It is transported in the plant as soluble sugars but stored asstarch - which is insoluble, so it cannot escape from the cells. The stored starch can be turned back into glucose later and used to release energy by respiration. Starch and glucose can also be used by the plant to make:
- cellulose for their cell walls
- proteins for growth and repair
- fats and oils for storage by the plant
Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.
