Does the Intensity of Light Affect the Rate of Photosynthesis?
… length of time a plant is exposed to sunlight affects photosynthesis I think it would be logical if the same applied to light intensity. I think that the nearer the light is to the plant, the more photosynthesis will occur, so more bubbles of oxygen will be given off. I think this will be relative – if the lamp is at 10cm there will be twice as many bubbles as if the lamp was at 20cm. The key variable is light intensity, adjusted by moving the lamp. We will then discover the effects of this. The same type of plant will be used each time as different plants may have different rates of photosynthesis. I will also use the same quantity of plant as more plant matter will do more photosynthesis. I will keep check of the temperature of the water by using a thermometer. The temperature needs to be controlled as the …
