This video from Curious George introduces students to the importance of skins, peels, and other fruit coverings, which help protect a fruit's precious cargo: seeds. Seeds are a plant's offspring. For plants to survive, they must distribute their seed...s in places where they stand a good chance of growing. Fruits are part of a plant's reproductive strategy. The teacher explains to the students that ripe fruit is more attractive to animals. This is important, as fruit-eating animals transport seeds contained inside fruit to other places, where they are deposited and subsequently germinate. Closed captioning included. Run time 01:26.
