Concept:Photosynthesis produces glucose, which increases the dry weight of a plant.Explanation:Green plants use carbon dioxide and water with light energy to make glucose and oxygen in the presence of chlorophyll.The equation is: 6CO2+6H2OlightchlorophyllC6H12O6+6O2Glucose is stored as starch and used for growth, so dry weight increases.Carbon dioxide enters leaves through stomata in bright light.The oxygen given off comes from the splitting of water.Only green plants can photosynthesize because chlorophyll is needed.Thus, claiming that plants can photosynthesize without an increase in dry weight is false.Answer:A. Plants can photosynthesize without an increase in dry weight
