思路引導 VIP
請試著回想看看，如果我們觀察一個果實的構造，發現它的外皮是由許多個「獨立的小單位」緊密癒合而成的，而這些單位在開花時期原本是生長在同一個花軸上的「多朵獨立花朵」，那麼這種果實的分類，會與從「單一朵花」發育出來的果實有所不同嗎？

恭喜你答對了！這題考驗的是對植物學中「果實分類」的精確掌握，你能精準分辨單生果、聚合果與多花果的差異，表現得非常出色。
被子植物果實的來源與分類
果實主要是由被子植物的子房 (ovary) 發育而來。在植物學定義中，豌豆莢 (I) 與番茄 (II) 都是由單一花朵中發育而成的典型果實。而桃子與堅果 (III) 雖然外觀與口感迥異，但本質上皆源自於單一花朵中的單一子房，因此都屬於「單生果 (simple fruit)」。這部分考驗的是基礎觀念的驗證，你能夠不受口感（多汁或乾燥）影響而做出正確判斷，基礎非常扎實。
