Answer:
1. Plants are green due to presence of green pigment chlorophyll in their chloroplasts.
2. ATP is used to make organic sugars (glucose)
Explanation:
Chlorophyll pigments absorb the light in the blue and red regions and reflect all the green light. When the reflected green light reaches our eyes, the plants look green in color. The color of the object is determined by the color of the reflected light. 
Splitting of water during the light-dependent phase of photosynthesis and electron transfer through cytochrome b6/f complex generates the proton concentration gradient which in turn drives the synthesis of ATP. Calvin cycle refers to the set of reactions that fix the atmospheric CO2 into organic sugars such as glucose. The ATP molecules formed during light reactions are used to drive the endergonic reactions of the Calvin cycle.
