Most of us have wondered about those tiny dots on the outside of a strawberry. With a closer look, the tiny dots appear to be seeds. But it turns out that those "seeds" are not what they seem -- they are actually small, dry fruits known as achenes, and each achene contains a single seed inside.
When a strawberry flower is pollinated, it forms numerous small fruits. The receptacle tissue swells and forms the red flesh of the strawberry -- which we erroneously call the "fruit." In reality, each "seed" we see on the outside of a strawberry actually represents an individual fruit making up the whole. Strawberries are fairly unique, because with most fruits, when the fruit flower is pollinated, the ovary swells and makes a fruit with a seed inside.
