Write an essay.
Why is NADPH said to have reducing power, and why is reducing power important to
photosynthesis?
Evaluate the role of photosynthesis in the flow of energy through an aquatic ecosystem.
Use to answer
Household chemicals are sometimes discarded in ways that allow the chemicals to enter lakes and streams. These diluted chemicals may affect the growth of aquatic plants or terrestrial plants growing beside the water. A student hypothesized that a particular household chemical would have a negative effect on the photosynthetic rate of plants. She assumed that the chemical would not kill the plants.
Question: Unit C - Design an experiment to determine whether a household chemical affects the rate of photosynthesis in plants .
Your response should include
• a detailed procedure • identification of the controlled, manipulated, and responding variables
• an explanation of evidence that you will collect and how it will be interpreted to determine the effect the chemical had on rate of photosynthesis
