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.

Explanation: photosynthetic plants possess a double membrane organelle called chloroplast.this chloroplast contains chlorophyll chlorophyll are the reason plants
are green,they are green pigments which absorbs wavelengths of sunlight that is used in the production of glucose and other products through photosynthesis.this glucose is converted to starch ,which is the form it is stored
