Why do strawberries grow thier seeds on the outside of them?
Having seeds on the outside make it easier for strawberries to get planted elsewhere. Birds eat them, fly to somewhere else, expel them, and the seed grows in the new place. It is a survival trait. The strawberry is an accessory fruit; that is, the fleshy part is derived not from the ovaries which are the “seeds” (actually achenes) but from the peg at the bottom of the hypanthium that held the ovaries. So from a technical standpoint, the seeds are the actual fruits of the plant, and the flesh of the strawberry is modified receptacle tissue. It is whitish-green as it develops and in most species turns red when ripe.
