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

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
