Astudent performed an experiment to demonstrate that a plant needs chlorophyll for photosynthesis. he used plants that had green leaves with white areas. after exposing the plants to sunlight, he removed a leaf from each plant and processed the leaves to remove the chlorophyll. he then tested each leaf for the presence of starch. starch was found in the area of the leaf that was green, and no starch was found in the area of the leaf that was white. he concluded that chlorophyll is necessary for photosynthesis.
which statement represents an assumption the student had to make in order to draw this conclusion?
(1) starch is synthesized from the glucose produced in the green areas of the leaf.
(2) starch is converted to chlorophyll in the green areas of the leaf.
(3) the white areas of the leaf do not have cells.
(4) the green areas of the leaf are heterotrophic.

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
