Fruit is characterized as the part of a plant that grows where a flower used to be, after the flower was pollinated and died.

The fruit contains the seeds, which can grow new plants. Fruits are often fleshy with juices and nutrients for animals to eat. After animals eat the fruit, they poop the seeds out somewhere new, and the seeds can grow into new plants.
