| | Fruit Summary |
 | | Fruits are formed from the ovary alone in many plants, but in other plants, adjacent tissues that are not part of the pistil may become part of the fruit. |
 | | Grains, or caryopses, are small, one-seeded fruits that have fruit walls that are fused to the seed and are therefore inseparable, as in corn. |
 | | Fruits may be dry in texture, such as those of the sunflower Helianthus annua, and the key-like fruits (or samaras) of the sugar maple (Acer saccharum); or they may be thick and fleshy, like the tomato (Lycopersicum esculentum), the apple (Malus pumila), and the watermelon (Citrullus vulgaris). |
