Shortage of carbon dioxide. Shortage of light. 5 of 9 Basic limiting factors Temperature. Carbon dioxide concentration. Light intensity. 6 of 9 Glucose produced in photosynthesis may be Used for respiration. Converted into insoluble starch for storage.Used to produce fat or oil for storage 7 of 9 Glucose produced in photosynthesis may be Used to produce cellulose, which strengthens the cell wall.Used to produce proteins. 8 of 9 Plants producing proteins They use nitrate ions that are absorbed from the soil. 9 of 9
