A strawberry isn’t an actual berry, but a banana is.
Botanically speaking, a berry has three distinct fleshy layers: the exocarp (outer skin), mesocarp (fleshy middle) and endocarp (innermost part, which holds the seeds).
Usually, people think of berries as small, squishy fruit that can be picked off plants, but the scientific classification is far more complex.
In order to be considered a berry, a fruit must develop from a flower that has one ovary. In addition, to be a berry, a fruit must have two or more seeds.
A strawberry is an aggregate fruit, the little yellow ovals on the fruit’s surface, which each contain a seed.
Like other berries, bananas are composed of three fleshy layers: the outer skin, the mushy middle and the innermost part with the seeds.
