Light intensity, carbon dioxide concentration, temperature 3 of 10 What is the glucose used for from photosynthesis? 1 - to release immediate energy through respiration in all plant cells 4 of 10 How do plants produce proteins for growth? To produce proteins, plants also use nitrate ions that are absorbed from the soil to make amino acids that are then joined to make proteins. 5 of 10 How could you increase the rate of photosynthesis in a greenhouse? Light bulbs 6 of 10 What are the two functions of bile? Neutralises the stomach acid to produce alkaline conditions so that enzymes in the small intestine are not denatured 7 of 10 What is an organ?
