Bananas are a popular fruit, botanically a berry, grown in tropical regions. They're rich in potassium, vitamin C, and fiber, with about 90-120 calories per medium fruit.
 
The scientific name is Musa, and they’re primarily produced in countries like India, China, and Indonesia. Ripening involves ethylene gas, turning them from green to yellow. They’re eaten raw, cooked, or used in baking (e.g., banana bread).
