Final answer:
The statement made by the banana expert is false. Bananas are curved due to negative geotropism, not because they grow towards the sun.
Step-by-step explanation:
The statement made by the banana expert is a logical fallacy. The expert claims that bananas are curved because they grow towards the sun. However, this statement is false. Bananas are curved due to a process called negative geotropism, which means they grow against gravity. The curved shape of bananas helps them distribute weight and maximize sunlight exposure.
