【英语时差8,16】水果及其种子-上

Usually a green, sour fruit is just a fruit that’s not ripe yet. If you left a lime on the tree longer would it eventually change color and become sweet, like an orange? Actually, limes do become much more yellow and less sour as they ripen¹. Under ripe limes are darker green and quite bitter. There are other clues to their ripeness too. Ripe limes are heavy with juice and more aromatic², with a fragrant³ “limey”smell. Aha, Most fruits we eat use similar cues to advertise ripeness.But why? Why would plants want parts of them to be eaten? Fruiting plants have evolved a partnership⁴ with certain animals in order to increase the success of their seeds.Tasty fruit pulp⁵ is the reward plants offer to animals in exchange for dispersing⁶ their seeds.
