Explore Plants grow everywhere. They grow on the ground, in water, and on many surfaces. Plants are producers and do photosynthesis and cellular respiration. When plants do photosynthesis, they use H20 (Water) and CO2 (Carbon Dioxide) as reactants. The products of photosynthesis are C6H12O6 (Glucose) and 02 (Oxygen). Plants and all organisms also do cellular respiration. The products of respiration are C6H12O6 (Glucose), CO2 (Carbon Dioxide), and ATP molecules (Energy). Photosynthesis and Cellular Respiration go in a cycle. The products of photosynthesis are the reactants of respiration and the other way around. A question I have about plants is how do plants gain their mass and how does ATP power the plant.
Research Question Firstly, does the species of a plant effect the rate of photosynthesis occurring? Secondly, does the temperature the plant is in increase or decrease the rate of photosynthesis?
Predictions Our predictions are that in room temperature water (21°C), the most spinach leaves will rise. In hot temperature water (32°), the second most leaves will rise, Finally, in the cold temperature water (12°C), the least leaves will rise.
Experimental Design Our plan is to get 3 cups of water, all with a tablespoon of baking soda to add CO2. Then we will cut spinach leaves into 30 disks. We will then drain the oxygen out of these disks using a syringe. We will then put 10 leaf disks in every cup. We will leave one cup in room temperature (21°C), one in submerged in cold ice (12°C), and one in a hot water bath (32°C). We will then record how many leaf disks float, recording data every minute for 10 minutes. Recording how many leaf disks float shows us how much photosynthesis is happening in each cup because oxygen is a product of photosynthesis oxygen causes the leaf disks to float. Our constant variables will be the CO2 level, amount of water, beaker used, thermometer used, and the amount/type of leaf disks. Our experimental variable is the temperature of the water. We will measure how many leaf disks float.
Conclusion In the room temperature water, the most leaf disks floated at the end. In the hot water, the second most leaf disks floated, and in the cold water the least leaf disks floated. We can conclude that the rate of photosynthesis of the leaf disks in the 21°C water was the highest, the rate of photosynthesis in the 32°C water was the second highest, and the 12°C water allowed the plant to undergo the least photosynthesis because the more photosynthesis a plant does, the more oxygen it produces, which makes the leaf disks float. Plants do photosynthesis slower in extreme temperatures and more when the water is at a moderate temperature.
