Final answer:
Engineers might look at the structure of leaves in plants when designing the arrangement of solar cells.
Step-by-step explanation:
When engineers are designing the way solar cells are arranged, they might look at the structure of leaves in plants. Leaves have a flat and broad surface area that allows them to capture sunlight efficiently. This characteristic can be used in designing solar cell arrangements to maximize sunlight exposure and energy collection.
