Question

1. in the demo with the color changing solution, we had two tubes - one with a leaf in it and one without. in our demo, both were put under a light and only the one with the leaf changed color. if we put both tubes in a box, instead of having a light on it...

a. the one with the leaf would have changed color, but the one without would not have changed color.
b. neither would have changed color.
c. the one with the leaf would not have changed color, but the one without would have changed color.
d. both would have changed color.

1. fill in the blanks in the diagram of photosynthesis below:

Explanation:

1. Photosynthesis requires light. When the tubes are put in a box without light, the leaf in one tube cannot perform photosynthesis to cause a color - change in the solution. So neither tube would change color.
2. Without the actual diagram and any given information about what should be filled in, we cannot answer this part. But for a photosynthesis diagram, the typical inputs are carbon dioxide ($CO_2$), water ($H_2O$), and light energy, and the outputs are oxygen ($O_2$) and glucose ($C_6H_{12}O_6$).

Answer:

1. b. Neither would have changed color.
2. No answer provided due to lack of diagram details.
