  • Petals and stamens fall away.
  • Seeds are dispersed.
  • Each seed contains a plant embryo.
  • A seed will sprout and become a new plant.

Simple Fruit - Cucumber

  • A female flower develops into the cucumber fruit.
  • The prickly inferior ovary develops into the cucumber.

Simple Fruit - Sunflower
