out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because light intensity

PLANTS Plants in Our Daily Life A plant(also called green plants) is a multi-cellular living organism‚member of kingdom Plantae.It is at the base of the food web and are Autotrophs.Plants are considered as backbone of all life on Earth and essential resource for living oragnisms.Plants can be reffered as a factory which processes light into energy and manufactures food for it ownself as well as for other living things.Scientists have foundmore than 270‚000 spieces of plants They include a host of

Effect of light on Silver Halide Salts Aim: To investigate the effect of sunlight and UV light on silver salts and to identify an application of this reaction. Hypothesis: The compounds exposed to sunlight (which already contains UV light) will decompose. The compounds which are not exposed to light (put in a dark place) will not decompose. Theory: Equipment: * 4 x petri dishes * 1 x glass stirring rod * 0.1 mol/L silver nitrate in a dropper bottle * 0.1 mol/L Sodium chloride

photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around a stem that form a chain of long
