Photosynthesis Experiment: Cell Energy Gizmo Answer Key
The Photosynthesis experiment in the Cell Energy Gizmo allows you to investigate the process of photosynthesis, which is how plants use sunlight to create energy in the form of sugar. By manipulating various factors that affect photosynthesis, you can observe the changes in the rate of photosynthesis and gain a better understanding of how this vital process works.
Variables and Data Collection
The following variables can be manipulated in the Photosynthesis experiment:
- Light intensity
- Carbon dioxide concentration
- Temperature
- Chlorophyll concentration
The following data is collected during the experiment:
- Rate of photosynthesis
- Oxygen production
- Carbon dioxide consumption
Results and Discussion
The results of the Photosynthesis experiment show that the rate of photosynthesis is affected by all of the manipulated variables. Light intensity, carbon dioxide concentration, and temperature all have a positive effect on the rate of photosynthesis, while chlorophyll concentration has a negative effect.
These results are consistent with our understanding of the process of photosynthesis. Light is required for photosynthesis to occur, and the more light that is available, the faster the rate of photosynthesis. Carbon dioxide is also required for photosynthesis, and the more carbon dioxide that is available, the faster the rate of photosynthesis.
Temperature also affects the rate of photosynthesis, with higher temperatures leading to faster rates of photosynthesis. Finally, chlorophyll is a pigment that absorbs light energy and is essential for photosynthesis. The more chlorophyll that is present, the more light energy can be absorbed and the faster the rate of photosynthesis.
Cellular Respiration Experiment
Cellular respiration is the process by which cells convert glucose into energy. This experiment allows students to investigate the factors that affect the rate of cellular respiration.
Procedure
- Set up the respirometer by adding 10 mL of glucose solution to the reaction chamber and 10 mL of water to the control chamber.
- Insert the respirometer into the water bath and connect it to the computer.
- Start the data collection software.
- Allow the reaction to proceed for 10 minutes.
- Stop the data collection software and record the data.
Variables
- Independent variable: concentration of glucose
- Dependent variable: rate of cellular respiration
- Controlled variables: temperature, pH, volume of glucose solution, volume of water
Results
The results of the experiment showed that the rate of cellular respiration increased as the concentration of glucose increased. This is because glucose is the substrate for cellular respiration, and the more glucose that is available, the faster the reaction will proceed.
Discussion
The results of this experiment support the hypothesis that the rate of cellular respiration is affected by the concentration of glucose. This experiment can be used to investigate other factors that affect the rate of cellular respiration, such as temperature, pH, and the presence of inhibitors.
Comparison of Photosynthesis and Cellular Respiration
Photosynthesis and cellular respiration are two essential processes that sustain life on Earth. While both involve the exchange of energy, they have distinct differences in their reactants, products, and overall purpose.
