A student hypothesized that the green color of plant leaves is related to exposure to sunlight and tested this hypothesis by placing a dark green plant in a dark closet. Three days later, the student discovered that the plant was a much lighter shade of green. Which statement is most likely the conclusion the student reached?
Answer
A
The hypothesis was not supported because the plant became a darker shade of green after not receiving any sunlight for three days.
B
The plant color was lighter after three days because it was kept in a dark closet.
C
The hypothesis was supported because the plant became a lighter shade of green after not receiving any sunlight for three days.
D
The plant color was darker after three days because it was kept in a dark closet.
Explanation
The plant was placed in darkness, so it did not receive sunlight. After three days, its leaves became lighter green, which supports the hypothesis that leaf color is related to sunlight exposure. Therefore, the student would most likely conclude that the hypothesis was supported.
