The shoot receives more light, so its tip can produce more auxin for growth
The stem is warmed by the light, so the enzymes in its cells work more quickly
The leaves absorb more light, so the rate of photosynthesis in the leaves increases
The leaves lose less water, because the extra light causes their stomata to close
