MODEL RELEASED. Student measuring oxygen produced by pond weed (lower left). As the pond weed photosynthesises it produces oxygen. This is collected and the volume measured in the photosynthometer (centre). The apparatus allows different conditions,which may affect the rate of photosynthesis,to be measured,such as the intensity of sunlight | |
