Step 1
Explain why it is important that the clear plastic cover is transparent.
Answer
The clear plastic cover must be transparent to allow sunlight to reach the carrot plants underneath.
Plants require light for photosynthesis, which is the process by which they convert sunlight into energy. In order for the plants to perform photosynthesis effectively, it is crucial that they receive an adequate amount of sunlight. A transparent cover enables light to penetrate and reach the leaves, ensuring that the plants can grow healthy and thrive.
