The fleshy, red part of the strawberry is actually accessory tissue, which is derived from the receptacle, the region where the whorls of the flower unit. Each pistil of the flower produced a single achene (hard, seed-like structures pressed into the red, fleshy portion). Although each achene looks like a seed, it is actually a one-seeded fruit. Overall, the strawberry is considered an aggregate fruit because it was formed from a single flower that had many pistils (an apocarpous gynoecium).
