Question

3. A student 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 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
a) Starch is synthesized from the glucose produced in the green areas of the leaf.
b) Starch is converted to chlorophyll in the green areas of the leaf.
The white areas of the leaf do not have cells.
d The green areas of the leaf are heterotrophic.

Answer 1

Answer:Starch is synthesized from the glucose produced in the green areas of the leaf.

Step-by-step explanation:

Answer 2

A.)
The student had to assume that starch was made from the glucose created in photosynthesis in order to conclude that no starch was present in the leaf areas that lacked chlorophyll and could not perform photosynthesis.
