Does raising the light intensity increase the rate of photosynthesis? :: Biology

Does raising the light lastingness increase the site of photosynthesis? m some other To see if raising the light intensity increases the rate ofphotosynthesis.PredictionI predict that raising the light intensity entrust increasethe rate of photosynthesis. I think this beca custom light is the mostimportant thing mandatory for photosynthesis. I then think that the rateof photosynthesis give stay the kindred when it reaches a certain point.I think this because the go down may use up all of the carbon dioxide(Sodium hydro change) and the plant can wealthy person as much light as itneeds but if it does not have any carbon dioxide it will not be ableto photosynthesise. The temperature in any case has to be right. If it is toohot the enzymes will be destroyed and the plant will not be able tophotosynthesise. The temperature and the amount of carbon dioxide argoncalled the limiting factors.I think a graph of the results would look standardized thisApparatus list* Piece of weed* Pa perclip* Sodium hydro carbonate* Water* Test pipage* Beaker* Lamp* Stopwatch* Scissors* Spatula* Meter see* Glass Rod* Measuring CylinderDiagramMethod1. hive up the equipment on the equipment list.2. Darken the room, so that the plant cannot use light for photosynthesising from other places.3. Cut a piece of weed that is about 5 cm long.4. Put a spatula measure of sodium hydro carbonate in a test vacuum tube with 40ml cold tap water and stir. This provides the plant with luxuriant CO2 to photosynthesise.5. Fill a 1000ml beaker with 700ml water and put the test tube into it. This will act as heat shield from the lamp, so that the temperature will not affect the try.6. Put the weed in the test tube with the cut end facing upwards.7. Put the lamp 10cm away form the beaker and deepen on.8. Leave the weed to adjust to the conditions for 1 arcsecond.9. Time one minute and count the bubbles coming out of the cut end of the leaf for 1 minute.10. Record the results in a t able.11. Then do the whole experiment 3 times for accuracy, then find the average and record in your table.12. Do the whole experiment 6 times for 20cm, 30cm, 40cm, 50cm, and 60cm away from the lamp. intermediate Test To make this a fair test I will not let any of thevariables change apart from the light intensity because this is part
