Step 1
Explain why it is important that the clear plastic cover is transparent.
Answer
The clear plastic cover is important because it allows light to reach the carrot plants underneath it.
Plants require light for photosynthesis, a process that enables them to convert sunlight into energy. If the cover were opaque, it would block this essential light, inhibiting photosynthesis and negatively affecting plant growth. Therefore, transparency is crucial for sustaining healthy plant development.
