Rate of photosynthesis Essay

I’m going to investigate the amount of light used in photosynthisis to see if ithas a noticable effect when you increase or decrease the light intensity. Photosynthisis is the way in which light and carbon-dioxide is used by a plant toproduce energy in the form of starch. 6CO + 6H O = C H O + 6OThe factors that effect the rate of photosynthisis are the amount of light, theamount of carbon-dioxide (CO ) and the temperature that can be used by the plant.

Ihave already carried out the experiment to see the effects on a plant when youchange the amount of carbon-dioxide. I found that the more carbon-dioxide used thefaster the plant photosynthisied. To see if this rule (More of a limiting factor = Thequiker the rate of photosynthisis) works, I will plan a experiment . My experimentwill be to see if the light intensity follows this rule.

I will use a aquatic plant as theycan be used to see the effects under water. These plants still cotain chlorophyll (alight absorbing die thats converts light energy intochemical energy). To see if the amount of light intensity will effect the rate of photosynsis. I predict that the more amount of light you allow the chlorophyll to absorb thequicker the rate of photosynthisis will be. I think this because the amount of light isa limiting factor in the reaction of photosynthisis.

So if you alow more of a limitingfactor to be present in the chemical reaction it will all most certainly speed up therate of that reaction. If a plant had the right amount of carbon-dioxide and the righttemperature but the wrong amount of light the reaction of photosynthisis will beslow. This is because the reaction needs the light to let the plant turn the lightPlace the pond weed Inside the upside down FunnelAdd 1 Spactular of Sodium Bicarbonate Inside the Upside Down FunnelSet the Lamp (thats connected to the power pack) to the Chosen distance Ethier 10,20,30,40,50cm away from the beakerStart the Stop Clock and time for three MinutesCount the Number Of Bubbles that the Pond Weed Gives off.Remember Repeat This Experiment 6 Times Using a Different distance EachTake results for the same amount of timeUse the same amount of sodium bicarbonateDistance of lamp Bubbles realised Average from the plant in 3 minutes A graph to show the effects of light to the rate of photosynthisis Bibliography: .
