Biological Research Problem: How does light affect the rate of photosynthesis? The Plan In my experiment I will see how light affects the rate of photosynthesis. To do this experiment I will set up the apparatus as shown in figure 1. The apparatus I will use is as follows: -1 tripod1 300ml beaker1 boiling tube1 clamp holder1 clamp1 leader1 ring binder1 lamp11 meter ruler1 thermometer1 stopwatchTo carry out the experiment experiment First I will install the device. First I will place the tripod over the base of the clamp stand and fill the 300ml beaker with 250ml of water to create the water bath. I will place the stud in the center of the bar on the caliper mount and place the caliper into the stud. I would then fill the boiling tube with 43ml of water, insert the duckweed and place it in the clamp. I would place the ring binder around the clamp holder surrounding the water base. Finally, I connected the lamp and positioned it 10 cm away from the lentil. I did a preliminary experiment to get an idea of ​​how to do the main, correct experiment and what would happen in the experiment. In the preliminary experiment we didn't use safety measures, so it wasn't a fair experiment. We did this because it gave us an idea of ​​what problems we might encounter when we did the main experiment and it gave us an idea of ​​how to do it. Duckweed should create photosynthesis by the following equation: -6CO2 + 6H2O 6C6H12O6+ 6O2Photosynthesis occurs when plants take in carbon dioxide from the surrounding air into the leaves and water from nearby soil into the roots. The leaves then take light energy from the sun, which is absorbed into the cells' chlorophyll and passes it on to be used in photosynthesis. Glucose is produced and is converted into starch for storage. Oxygen is produced from water and is a waste product so it is released into the air. The plant uses carbon dioxide and water to create carbohydrates. Glucose is a small soluble molecule that is useless for a plant to use as energy but it converts it to starch, which is a large, insoluble molecule, so it can be stored to be converted back into glucose. I made this experiment as fair as possible.
