root growth reproduction photosynthesis water absorption
I gave my students this multiple choice question: Janet learns that Earth is tilted. Due to its tilt, some areas on the surface of Earth experience darkness for an entire day. Which plant process is affected most during this darkness?

Only one answer is correct among these 4 choices:
- root growth
- reproduction
- photosynthesis
- water absorption

Could you tell me which one is correct?

photosynthesis
