Question

is a banana a berry

Answer 1

Yes — botanically a banana is a berry.

Botanical berries develop from a single ovary of one flower, have a fleshy pericarp throughout, and contain one or more seeds embedded in the flesh. Bananas meet that definition (cultivated bananas are parthenocarpic, so their seeds are tiny or absent). By contrast, common “berries” in the kitchen — strawberries and raspberries — are not true botanical berries (strawberries are accessory fruits with achenes; raspberries are aggregates of drupelets).
