– Statement II provides a scientific fact: Chlorophyll, the pigment responsible for the green color in plants, requires sunlight for its synthesis. This process is part of photosynthesis.
– The paleness of the grass (loss of green color) occurs because the brick blocks sunlight, preventing the grass from synthesizing chlorophyll. Without chlorophyll, the green pigment is absent or significantly reduced. Therefore, Statement II directly explains why Statement I occurs.
